## **Overview**

PowerPoint stores equations as Office Math Markup Language (OMML). With Aspose.Slides for Python via Java, you can create the same kind of math content programmatically: fractions, radicals, functions, limits, N-ary operators, matrices, arrays, and formatted math blocks.

In PowerPoint, users normally add equations from **Insert > Equation**:

![PowerPoint Insert tab with the Equation command selected](powerpoint-math-equations_1.png)

The result is editable math text on the slide:

![A PowerPoint slide containing an editable math equation](powerpoint-math-equations_2.png)

Aspose.Slides builds that math text through three main objects:

- A math shape, created with [addMathShape](https://reference.aspose.com/slides/python-java/aspose.slides/shapecollection/#addMathShape), is the shape that contains the equation.
- [MathPortion](https://reference.aspose.com/slides/python-java/aspose.slides/mathportion/) stores math content inside the shape text frame.
- [MathParagraph](https://reference.aspose.com/slides/python-java/aspose.slides/mathparagraph/) contains one or more [MathBlock](https://reference.aspose.com/slides/python-java/aspose.slides/mathblock/) objects.

Most examples below use [MathematicalText](https://reference.aspose.com/slides/python-java/aspose.slides/mathematicaltext/) and the fluent methods from [MathElementBase](https://reference.aspose.com/slides/python-java/aspose.slides/mathelementbase/) to keep the code short and readable.

For MathML export scenarios, see [Export Math Equations from Presentations in Python](/slides/python-java/exporting-math-equations/).

## **Create an Equation**

This example creates a math shape and adds the Pythagorean theorem:

![The equation c squared equals a squared plus b squared](powerpoint-math-equations_3.png)

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import MathematicalText, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    math_shape = slide.getShapes().addMathShape(20, 20, 700, 120)
    math_paragraph = math_shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getMathParagraph()

    a_squared = MathematicalText("a").setSuperscript("2")
    b_squared = MathematicalText("b").setSuperscript("2")
    equation = MathematicalText("c").setSuperscript("2").join("=").join(a_squared).join("+").join(b_squared)

    math_paragraph.add(equation)

    presentation.save("pythagorean-theorem.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

{{% alert color="info" title="Note" %}}

[addMathShape](https://reference.aspose.com/slides/python-java/aspose.slides/shapecollection/#addMathShape) creates a shape that already contains a math paragraph. Access the first [MathPortion](https://reference.aspose.com/slides/python-java/aspose.slides/mathportion/), get its [MathParagraph](https://reference.aspose.com/slides/python-java/aspose.slides/mathparagraph/), and add math blocks or math elements to it.

{{% /alert %}}

## **Add Fractions**

Use [divide](https://reference.aspose.com/slides/python-java/aspose.slides/mathelementbase/#divide) to create a fraction. You can choose a fraction style with [MathFractionTypes](https://reference.aspose.com/slides/python-java/aspose.slides/mathfractiontypes/).

![A skewed math fraction showing one divided by x](powerpoint-math-equations_4.png)

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import MathBlock, MathFractionTypes, MathematicalText, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    math_shape = slide.getShapes().addMathShape(20, 20, 700, 100)
    math_paragraph = math_shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getMathParagraph()

    fraction = MathematicalText("1").divide("x", MathFractionTypes.Skewed)

    math_block = MathBlock(fraction)
    math_paragraph.add(math_block)

    presentation.save("fraction.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

For a stacked fraction, use [MathFractionTypes.Bar](https://reference.aspose.com/slides/python-java/aspose.slides/mathfractiontypes/#Bar):

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import MathFractionTypes, MathematicalText

stacked_fraction = MathematicalText("x + 1").divide("y - 1", MathFractionTypes.Bar)
```

## **Add Radicals**

Use [radical](https://reference.aspose.com/slides/python-java/aspose.slides/mathelementbase/#radical) to create a square root, cube root, or other root. The current element becomes the base, and the argument becomes the degree.

![An n-th root radical expression with x under the radical sign](powerpoint-math-equations_5.png)

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import MathBlock, MathematicalText, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    math_shape = slide.getShapes().addMathShape(20, 20, 700, 100)
    math_paragraph = math_shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getMathParagraph()

    radical = MathematicalText("x").radical("n")

    math_block = MathBlock(radical)
    math_paragraph.add(math_block)

    presentation.save("radical.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

## **Add Functions and Limits**

Use [asArgumentOfFunction](https://reference.aspose.com/slides/python-java/aspose.slides/mathelementbase/#asArgumentOfFunction) or [function](https://reference.aspose.com/slides/python-java/aspose.slides/mathelementbase/#function) for functions such as `sin(x)`, `log(x)`, or custom function names. For limits, put `lim` in a [MathLimit](https://reference.aspose.com/slides/python-java/aspose.slides/mathlimit/) or use [setLowerLimit](https://reference.aspose.com/slides/python-java/aspose.slides/mathelementbase/#setLowerLimit).

![The limit of x as x approaches infinity](powerpoint-math-equations_8.png)

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import MathBlock, MathematicalText, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    math_shape = slide.getShapes().addMathShape(20, 20, 700, 100)
    math_paragraph = math_shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getMathParagraph()

    limit = MathematicalText("lim").setLowerLimit("x\u2192\u221E").function("x")

    math_block = MathBlock(limit)
    math_paragraph.add(math_block)

    presentation.save("functions-and-limits.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

For a custom function name, make the function name the current element:

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import MathematicalText

custom_function = MathematicalText("f").function("x + 1")
```

## **Add N-ary Operators and Integrals**

Use [nary](https://reference.aspose.com/slides/python-java/aspose.slides/mathelementbase/#nary) for summations, unions, intersections, and other large operators. Use [integral](https://reference.aspose.com/slides/python-java/aspose.slides/mathelementbase/#integral) for integrals. Both methods let you set lower and upper limits.

![A summation with lower and upper limits](powerpoint-math-equations_7.png)

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import MathBlock, MathNaryOperatorTypes, MathematicalText, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    math_shape = slide.getShapes().addMathShape(20, 20, 700, 120)
    math_paragraph = math_shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getMathParagraph()

    a_power = MathematicalText("a").setSuperscript("n-k")
    summation_base = MathematicalText("x").setSuperscript("k").join(a_power)

    summation = summation_base.nary(MathNaryOperatorTypes.Summation, "k=0", "n")

    math_block = MathBlock(summation)
    math_paragraph.add(math_block)

    presentation.save("nary-operators.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

N-ary operators are for large operators with optional limits. Simple operators such as `+`, `-`, and `=` are usually added as [MathematicalText](https://reference.aspose.com/slides/python-java/aspose.slides/mathematicaltext/) and joined into the expression.

For an integral, use [integral](https://reference.aspose.com/slides/python-java/aspose.slides/mathelementbase/#integral):

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import MathIntegralTypes, MathematicalText

differential = MathematicalText("dx").toBox()
integral_base = MathematicalText("x").join(differential)
integral = integral_base.integral(MathIntegralTypes.Simple, "0", "1")
```

## **Add Matrices**

Use [MathMatrix](https://reference.aspose.com/slides/python-java/aspose.slides/mathmatrix/) for rows and columns. Matrices do not include brackets by default, so enclose the matrix when you need parentheses, brackets, or braces.

![A two-row math matrix with one empty cell](powerpoint-math-equations_10.png)

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import MathBlock, MathMatrix, MathematicalText, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    math_shape = slide.getShapes().addMathShape(20, 20, 700, 120)
    math_paragraph = math_shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getMathParagraph()

    matrix = MathMatrix(2, 3)
    cell_0_0 = MathematicalText("1")
    matrix.set_Item(0, 0, cell_0_0)
    cell_0_1 = MathematicalText("x")
    matrix.set_Item(0, 1, cell_0_1)
    cell_1_0 = MathematicalText("x")
    matrix.set_Item(1, 0, cell_1_0)
    cell_1_1 = MathematicalText("2")
    matrix.set_Item(1, 1, cell_1_1)
    cell_1_2 = MathematicalText("y")
    matrix.set_Item(1, 2, cell_1_2)

    math_block = MathBlock(matrix)
    math_paragraph.add(math_block)

    presentation.save("matrix.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

## **Add Equation Arrays**

Use [toMathArray](https://reference.aspose.com/slides/python-java/aspose.slides/mathelementbase/#toMathArray) when you need aligned equations or a vertical stack of expressions.

![A vertical math array with x above y](powerpoint-math-equations_11.png)

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import MathBlock, MathematicalText, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    math_shape = slide.getShapes().addMathShape(20, 20, 700, 140)
    math_paragraph = math_shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getMathParagraph()

    equation_array = MathematicalText("x").join("y").toMathArray()

    math_block = MathBlock(equation_array)
    math_paragraph.add(math_block)

    presentation.save("equation-array.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

## **Add Trigonometric Functions**

Use [asArgumentOfFunction](https://reference.aspose.com/slides/python-java/aspose.slides/mathelementbase/#asArgumentOfFunction) when the argument is the current element and the function name is known.

![The trigonometric function cos applied to 2x](powerpoint-math-equations_6.png)

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import MathBlock, MathFunctionsOfOneArgument, MathematicalText, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    math_shape = slide.getShapes().addMathShape(20, 20, 700, 100)
    math_paragraph = math_shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getMathParagraph()

    cosine = MathematicalText("2x").asArgumentOfFunction(MathFunctionsOfOneArgument.Cos)

    math_block = MathBlock(cosine)
    math_paragraph.add(math_block)

    presentation.save("trigonometric-function.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

## **Add Subscripts and Superscripts**

Use the subscript and superscript helpers for indexes and powers. When the indexes must appear on the left side of the base, use [setSubSuperscriptOnTheLeft](https://reference.aspose.com/slides/python-java/aspose.slides/mathelementbase/#setSubSuperscriptOnTheLeft).

![A capital Y with left-side subscript 1 and superscript n](powerpoint-math-equations_9.png)

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import MathBlock, MathematicalText, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    math_shape = slide.getShapes().addMathShape(20, 20, 700, 100)
    math_paragraph = math_shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getMathParagraph()

    scripts = MathematicalText("Y").setSubSuperscriptOnTheLeft("1", "n")

    math_block = MathBlock(scripts)
    math_paragraph.add(math_block)

    presentation.save("subscript-superscript.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

## **Add Delimiters**

Use [enclose](https://reference.aspose.com/slides/python-java/aspose.slides/mathelementbase/#enclose) to put an expression inside delimiters. You can also set a separator character for delimiter expressions that contain several elements.

![A delimiter expression containing x, y, and z separated by vertical bars](powerpoint-math-equations_13.png)

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import MathBlock, MathematicalText, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    math_shape = slide.getShapes().addMathShape(20, 20, 700, 100)
    math_paragraph = math_shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getMathParagraph()

    delimiter = MathematicalText("x").join("y").join("z").enclose('<', '>')
    delimiter.setSeparatorCharacter('|')

    math_block = MathBlock(delimiter)
    math_paragraph.add(math_block)

    presentation.save("delimiters.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

## **Add a Border Box**

Use [toBorderBox](https://reference.aspose.com/slides/python-java/aspose.slides/mathelementbase/#toBorderBox) when the equation itself should be framed.

![A boxed equation showing a squared equals b squared plus c squared](powerpoint-math-equations_12.png)

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import MathBlock, MathematicalText, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    math_shape = slide.getShapes().addMathShape(20, 20, 700, 100)
    math_paragraph = math_shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getMathParagraph()

    b_squared = MathematicalText("b").setSuperscript("2")
    c_squared = MathematicalText("c").setSuperscript("2")
    boxed_equation = MathematicalText("a").setSuperscript("2").join("=").join(b_squared).join("+").join(c_squared).toBorderBox()

    math_block = MathBlock(boxed_equation)
    math_paragraph.add(math_block)

    presentation.save("border-box.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

## **Group Terms**

Use [group](https://reference.aspose.com/slides/python-java/aspose.slides/mathelementbase/#group) to place a grouping character above or below an expression. Add a limit to label the grouped terms.

![The expression x plus y grouped with the label any text below it](powerpoint-math-equations_15.png)

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import MathBlock, MathTopBotPositions, MathematicalText, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    math_shape = slide.getShapes().addMathShape(20, 20, 700, 120)
    math_paragraph = math_shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getMathParagraph()

    grouped = MathematicalText("x + y").group('\u23DF', MathTopBotPositions.Bottom, MathTopBotPositions.Top).setLowerLimit("any text")

    math_block = MathBlock(grouped)
    math_paragraph.add(math_block)

    presentation.save("grouped-terms.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

## **Format Math Elements**

Use formatting helpers only where they clarify the formula. For example, [overbar](https://reference.aspose.com/slides/python-java/aspose.slides/mathelementbase/#overbar) places a bar above a math element.

![A math expression ABC with an overbar](powerpoint-math-equations_14.png)

```python
import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import MathBlock, MathematicalText, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    math_shape = slide.getShapes().addMathShape(20, 20, 700, 100)
    math_paragraph = math_shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getMathParagraph()

    overbar = MathematicalText("ABC").overbar()

    math_block = MathBlock(overbar)
    math_paragraph.add(math_block)

    presentation.save("overbar.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```

## **FAQ**

**Can I edit an existing PowerPoint equation?**

Yes. Open the presentation, find the shape that contains a [MathPortion](https://reference.aspose.com/slides/python-java/aspose.slides/mathportion/), get its [MathParagraph](https://reference.aspose.com/slides/python-java/aspose.slides/mathparagraph/), and update the math blocks in that paragraph.

**Are equations saved as editable PowerPoint math?**

Yes. When you save to PPTX, Aspose.Slides writes the equation as editable Office math content.

**Can I export equations to LaTeX?**

Yes. Get the equation's [MathParagraph](https://reference.aspose.com/slides/python-java/aspose.slides/mathparagraph/) from its [MathPortion](https://reference.aspose.com/slides/python-java/aspose.slides/mathportion/), and call [MathParagraph.toLatex](https://reference.aspose.com/slides/python-java/aspose.slides/mathparagraph/#toLatex) to export it directly. For a complete example, see [Export Math Equations from Presentations in Python](/slides/python-java/exporting-math-equations/#export-math-equations-to-latex).
