## **Overview**

PowerPoint stores equations as Office Math Markup Language (OMML). With Aspose.Slides for 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/java/com.aspose.slides/ishapecollection/#addMathShape-float-float-float-float-), is the shape that contains the equation.
- [MathPortion](https://reference.aspose.com/slides/java/com.aspose.slides/mathportion/) stores math content inside the shape text frame.
- [MathParagraph](https://reference.aspose.com/slides/java/com.aspose.slides/mathparagraph/) contains one or more [MathBlock](https://reference.aspose.com/slides/java/com.aspose.slides/mathblock/) objects.

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

For MathML export scenarios, see [Export Math Equations from Presentations in Java](/slides/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)

```java
Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    IAutoShape mathShape = slide.getShapes().addMathShape(20, 20, 700, 120);
    IMathParagraph mathParagraph = ((MathPortion) mathShape.getTextFrame().getParagraphs()
            .get_Item(0).getPortions().get_Item(0)).getMathParagraph();

    IMathBlock equation = new MathematicalText("c")
            .setSuperscript("2")
            .join("=")
            .join(new MathematicalText("a").setSuperscript("2"))
            .join("+")
            .join(new MathematicalText("b").setSuperscript("2"));

    mathParagraph.add(equation);

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

`addMathShape` creates a shape that already contains a math paragraph. Access the first `MathPortion`, get its `MathParagraph`, and add math blocks or math elements to it.

## **Add Fractions**

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

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

```java
Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    IAutoShape mathShape = slide.getShapes().addMathShape(20, 20, 700, 100);
    IMathParagraph mathParagraph = ((MathPortion) mathShape.getTextFrame().getParagraphs()
            .get_Item(0).getPortions().get_Item(0)).getMathParagraph();

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

    mathParagraph.add(new MathBlock(fraction));

    presentation.save("fraction.pptx", SaveFormat.Pptx);
} finally {
    presentation.dispose();
}
```

For a stacked fraction, use `MathFractionTypes.Bar`:

```java
IMathFraction stackedFraction = new MathematicalText("x + 1").divide("y - 1", MathFractionTypes.Bar);
```

## **Add Radicals**

Use `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)

```java
Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    IAutoShape mathShape = slide.getShapes().addMathShape(20, 20, 700, 100);
    IMathParagraph mathParagraph = ((MathPortion) mathShape.getTextFrame().getParagraphs()
            .get_Item(0).getPortions().get_Item(0)).getMathParagraph();

    IMathRadical radical = new MathematicalText("x")
            .radical("n");

    mathParagraph.add(new MathBlock(radical));

    presentation.save("radical.pptx", SaveFormat.Pptx);
} finally {
    presentation.dispose();
}
```

## **Add Functions and Limits**

Use `asArgumentOfFunction` or `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/java/com.aspose.slides/mathlimit/) or use `setLowerLimit`.

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

```java
Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    IAutoShape mathShape = slide.getShapes().addMathShape(20, 20, 700, 100);
    IMathParagraph mathParagraph = ((MathPortion) mathShape.getTextFrame().getParagraphs()
            .get_Item(0).getPortions().get_Item(0)).getMathParagraph();

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

    mathParagraph.add(new MathBlock(limit));

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

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

```java
IMathFunction customFunction = new MathematicalText("f").function("x + 1");
```

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

Use `nary` for summations, unions, intersections, and other large operators. Use `integral` for integrals. Both methods let you set lower and upper limits.

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

```java
Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    IAutoShape mathShape = slide.getShapes().addMathShape(20, 20, 700, 120);
    IMathParagraph mathParagraph = ((MathPortion) mathShape.getTextFrame().getParagraphs()
            .get_Item(0).getPortions().get_Item(0)).getMathParagraph();

    IMathBlock summationBase = new MathematicalText("x")
            .setSuperscript("k")
            .join(new MathematicalText("a").setSuperscript("n-k"));

    IMathNaryOperator summation = summationBase.nary(MathNaryOperatorTypes.Summation, "k=0", "n");

    mathParagraph.add(new MathBlock(summation));

    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` and joined into the expression.

For an integral, use `integral`:

```java
IMathBlock integralBase = new MathematicalText("x").join(new MathematicalText("dx").toBox());
IMathNaryOperator integral = integralBase.integral(MathIntegralTypes.Simple, "0", "1");
```

## **Add Matrices**

Use [MathMatrix](https://reference.aspose.com/slides/java/com.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)

```java
Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    IAutoShape mathShape = slide.getShapes().addMathShape(20, 20, 700, 120);
    IMathParagraph mathParagraph = ((MathPortion) mathShape.getTextFrame().getParagraphs()
            .get_Item(0).getPortions().get_Item(0)).getMathParagraph();

    MathMatrix matrix = new MathMatrix(2, 3);
    matrix.set_Item(0, 0, new MathematicalText("1"));
    matrix.set_Item(0, 1, new MathematicalText("x"));
    matrix.set_Item(1, 0, new MathematicalText("x"));
    matrix.set_Item(1, 1, new MathematicalText("2"));
    matrix.set_Item(1, 2, new MathematicalText("y"));

    mathParagraph.add(new MathBlock(matrix));

    presentation.save("matrix.pptx", SaveFormat.Pptx);
} finally {
    presentation.dispose();
}
```

## **Add Equation Arrays**

Use `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)

```java
Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    IAutoShape mathShape = slide.getShapes().addMathShape(20, 20, 700, 140);
    IMathParagraph mathParagraph = ((MathPortion) mathShape.getTextFrame().getParagraphs()
            .get_Item(0).getPortions().get_Item(0)).getMathParagraph();

    IMathArray equationArray = new MathematicalText("x")
            .join("y")
            .toMathArray();

    mathParagraph.add(new MathBlock(equationArray));

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

## **Add Trigonometric Functions**

Use `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)

```java
Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    IAutoShape mathShape = slide.getShapes().addMathShape(20, 20, 700, 100);
    IMathParagraph mathParagraph = ((MathPortion) mathShape.getTextFrame().getParagraphs()
            .get_Item(0).getPortions().get_Item(0)).getMathParagraph();

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

    mathParagraph.add(new MathBlock(cosine));

    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`.

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

```java
Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    IAutoShape mathShape = slide.getShapes().addMathShape(20, 20, 700, 100);
    IMathParagraph mathParagraph = ((MathPortion) mathShape.getTextFrame().getParagraphs()
            .get_Item(0).getPortions().get_Item(0)).getMathParagraph();

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

    mathParagraph.add(new MathBlock(scripts));

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

## **Add Delimiters**

Use `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)

```java
Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    IAutoShape mathShape = slide.getShapes().addMathShape(20, 20, 700, 100);
    IMathParagraph mathParagraph = ((MathPortion) mathShape.getTextFrame().getParagraphs()
            .get_Item(0).getPortions().get_Item(0)).getMathParagraph();

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

    mathParagraph.add(new MathBlock(delimiter));

    presentation.save("delimiters.pptx", SaveFormat.Pptx);
} finally {
    presentation.dispose();
}
```

## **Add a Border Box**

Use `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)

```java
Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    IAutoShape mathShape = slide.getShapes().addMathShape(20, 20, 700, 100);
    IMathParagraph mathParagraph = ((MathPortion) mathShape.getTextFrame().getParagraphs()
            .get_Item(0).getPortions().get_Item(0)).getMathParagraph();

    IMathBorderBox boxedEquation = new MathematicalText("a")
            .setSuperscript("2")
            .join("=")
            .join(new MathematicalText("b").setSuperscript("2"))
            .join("+")
            .join(new MathematicalText("c").setSuperscript("2"))
            .toBorderBox();

    mathParagraph.add(new MathBlock(boxedEquation));

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

## **Group Terms**

Use `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)

```java
Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    IAutoShape mathShape = slide.getShapes().addMathShape(20, 20, 700, 120);
    IMathParagraph mathParagraph = ((MathPortion) mathShape.getTextFrame().getParagraphs()
            .get_Item(0).getPortions().get_Item(0)).getMathParagraph();

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

    mathParagraph.add(new MathBlock(grouped));

    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` places a bar above a math element.

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

```java
Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    IAutoShape mathShape = slide.getShapes().addMathShape(20, 20, 700, 100);
    IMathParagraph mathParagraph = ((MathPortion) mathShape.getTextFrame().getParagraphs()
            .get_Item(0).getPortions().get_Item(0)).getMathParagraph();

    IMathBar overbar = new MathematicalText("ABC").overbar();

    mathParagraph.add(new MathBlock(overbar));

    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`, get its `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?

Aspose.Slides exports math equations to MathML. If you need LaTeX, export to MathML first and then convert MathML with a tool that supports your target LaTeX dialect.
