## **Overview**

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

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

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

```php
$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $mathShape = $slide->getShapes()->addMathShape(20, 20, 700, 120);
    $mathParagraph = $mathShape->getTextFrame()->getParagraphs()
        ->get_Item(0)->getPortions()->get_Item(0)->getMathParagraph();

    $equation = (new MathematicalText("c"))
        ->setSuperscript("2")
        ->join("=")
        ->join((new MathematicalText("a"))->setSuperscript("2"))
        ->join("+")
        ->join((new MathematicalText("b"))->setSuperscript("2"));

    $mathParagraph->add($equation);

    $presentation->save("pythagorean-theorem.pptx", SaveFormat::Pptx);
} finally {
    if (!java_is_null($presentation)) {
        $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`](https://reference.aspose.com/slides/php-java/aspose.slides/mathelementbase/) to create a fraction. You can choose a fraction style with [MathFractionTypes](https://reference.aspose.com/slides/php-java/aspose.slides/mathfractiontypes/).

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

```php
$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $mathShape = $slide->getShapes()->addMathShape(20, 20, 700, 100);
    $mathParagraph = $mathShape->getTextFrame()->getParagraphs()
        ->get_Item(0)->getPortions()->get_Item(0)->getMathParagraph();

    $fraction = (new MathematicalText("1"))
        ->divide("x", MathFractionTypes::Skewed);

    $mathParagraph->add(new MathBlock($fraction));

    $presentation->save("fraction.pptx", SaveFormat::Pptx);
} finally {
    if (!java_is_null($presentation)) {
        $presentation->dispose();
    }
}
```

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

```php
$stackedFraction = (new MathematicalText("x + 1"))->divide("y - 1", MathFractionTypes::Bar);
```

## **Add Radicals**

Use [`radical`](https://reference.aspose.com/slides/php-java/aspose.slides/mathelementbase/) 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)

```php
$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $mathShape = $slide->getShapes()->addMathShape(20, 20, 700, 100);
    $mathParagraph = $mathShape->getTextFrame()->getParagraphs()
        ->get_Item(0)->getPortions()->get_Item(0)->getMathParagraph();

    $radical = (new MathematicalText("x"))
        ->radical("n");

    $mathParagraph->add(new MathBlock($radical));

    $presentation->save("radical.pptx", SaveFormat::Pptx);
} finally {
    if (!java_is_null($presentation)) {
        $presentation->dispose();
    }
}
```

## **Add Functions and Limits**

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

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

```php
$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $mathShape = $slide->getShapes()->addMathShape(20, 20, 700, 100);
    $mathParagraph = $mathShape->getTextFrame()->getParagraphs()
        ->get_Item(0)->getPortions()->get_Item(0)->getMathParagraph();

    $limit = (new MathematicalText("lim"))
        ->setLowerLimit("x\u{2192}\u{221E}")
        ->function("x");

    $mathParagraph->add(new MathBlock($limit));

    $presentation->save("functions-and-limits.pptx", SaveFormat::Pptx);
} finally {
    if (!java_is_null($presentation)) {
        $presentation->dispose();
    }
}
```

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

```php
$customFunction = (new MathematicalText("f"))->function("x + 1");
```

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

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

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

```php
$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $mathShape = $slide->getShapes()->addMathShape(20, 20, 700, 120);
    $mathParagraph = $mathShape->getTextFrame()->getParagraphs()
        ->get_Item(0)->getPortions()->get_Item(0)->getMathParagraph();

    $summationBase = (new MathematicalText("x"))
        ->setSuperscript("k")
        ->join((new MathematicalText("a"))->setSuperscript("n-k"));

    $summation = $summationBase->nary(MathNaryOperatorTypes::Summation, "k=0", "n");

    $mathParagraph->add(new MathBlock($summation));

    $presentation->save("nary-operators.pptx", SaveFormat::Pptx);
} finally {
    if (!java_is_null($presentation)) {
        $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`:

```php
$integralBase = (new MathematicalText("x"))->join((new MathematicalText("dx"))->toBox());
$integral = $integralBase->integral(MathIntegralTypes::Simple, "0", "1");
```

## **Add Matrices**

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

```php
$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $mathShape = $slide->getShapes()->addMathShape(20, 20, 700, 120);
    $mathParagraph = $mathShape->getTextFrame()->getParagraphs()
        ->get_Item(0)->getPortions()->get_Item(0)->getMathParagraph();

    $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));

    $presentation->save("matrix.pptx", SaveFormat::Pptx);
} finally {
    if (!java_is_null($presentation)) {
        $presentation->dispose();
    }
}
```

## **Add Equation Arrays**

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

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

```php
$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $mathShape = $slide->getShapes()->addMathShape(20, 20, 700, 140);
    $mathParagraph = $mathShape->getTextFrame()->getParagraphs()
        ->get_Item(0)->getPortions()->get_Item(0)->getMathParagraph();

    $equationArray = (new MathematicalText("x"))
        ->join("y")
        ->toMathArray();

    $mathParagraph->add(new MathBlock($equationArray));

    $presentation->save("equation-array.pptx", SaveFormat::Pptx);
} finally {
    if (!java_is_null($presentation)) {
        $presentation->dispose();
    }
}
```

## **Add Trigonometric Functions**

Use [`asArgumentOfFunction`](https://reference.aspose.com/slides/php-java/aspose.slides/mathelementbase/) 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)

```php
$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $mathShape = $slide->getShapes()->addMathShape(20, 20, 700, 100);
    $mathParagraph = $mathShape->getTextFrame()->getParagraphs()
        ->get_Item(0)->getPortions()->get_Item(0)->getMathParagraph();

    $cosine = (new MathematicalText("2x"))
        ->asArgumentOfFunction(MathFunctionsOfOneArgument::Cos);

    $mathParagraph->add(new MathBlock($cosine));

    $presentation->save("trigonometric-function.pptx", SaveFormat::Pptx);
} finally {
    if (!java_is_null($presentation)) {
        $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/php-java/aspose.slides/mathelementbase/).

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

```php
$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $mathShape = $slide->getShapes()->addMathShape(20, 20, 700, 100);
    $mathParagraph = $mathShape->getTextFrame()->getParagraphs()
        ->get_Item(0)->getPortions()->get_Item(0)->getMathParagraph();

    $scripts = (new MathematicalText("Y"))
        ->setSubSuperscriptOnTheLeft("1", "n");

    $mathParagraph->add(new MathBlock($scripts));

    $presentation->save("subscript-superscript.pptx", SaveFormat::Pptx);
} finally {
    if (!java_is_null($presentation)) {
        $presentation->dispose();
    }
}
```

## **Add Delimiters**

Use [`enclose`](https://reference.aspose.com/slides/php-java/aspose.slides/mathelementbase/) 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)

```php
$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $mathShape = $slide->getShapes()->addMathShape(20, 20, 700, 100);
    $mathParagraph = $mathShape->getTextFrame()->getParagraphs()
        ->get_Item(0)->getPortions()->get_Item(0)->getMathParagraph();

    $delimiter = (new MathematicalText("x"))
        ->join("y")
        ->join("z")
        ->enclose(new Java("java.lang.Character", "<"), new Java("java.lang.Character", ">"));
    $delimiter->setSeparatorCharacter(new Java("java.lang.Character", "|"));

    $mathParagraph->add(new MathBlock($delimiter));

    $presentation->save("delimiters.pptx", SaveFormat::Pptx);
} finally {
    if (!java_is_null($presentation)) {
        $presentation->dispose();
    }
}
```

## **Add a Border Box**

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

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

```php
$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $mathShape = $slide->getShapes()->addMathShape(20, 20, 700, 100);
    $mathParagraph = $mathShape->getTextFrame()->getParagraphs()
        ->get_Item(0)->getPortions()->get_Item(0)->getMathParagraph();

    $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));

    $presentation->save("border-box.pptx", SaveFormat::Pptx);
} finally {
    if (!java_is_null($presentation)) {
        $presentation->dispose();
    }
}
```

## **Group Terms**

Use [`group`](https://reference.aspose.com/slides/php-java/aspose.slides/mathelementbase/) 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)

```php
$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $mathShape = $slide->getShapes()->addMathShape(20, 20, 700, 120);
    $mathParagraph = $mathShape->getTextFrame()->getParagraphs()
        ->get_Item(0)->getPortions()->get_Item(0)->getMathParagraph();

    $grouped = (new MathematicalText("x + y"))
        ->group(new Java("java.lang.Character", "\u{23DF}"), MathTopBotPositions::Bottom, MathTopBotPositions::Top)
        ->setLowerLimit("any text");

    $mathParagraph->add(new MathBlock($grouped));

    $presentation->save("grouped-terms.pptx", SaveFormat::Pptx);
} finally {
    if (!java_is_null($presentation)) {
        $presentation->dispose();
    }
}
```

## **Format Math Elements**

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

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

```php
$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $mathShape = $slide->getShapes()->addMathShape(20, 20, 700, 100);
    $mathParagraph = $mathShape->getTextFrame()->getParagraphs()
        ->get_Item(0)->getPortions()->get_Item(0)->getMathParagraph();

    $overbar = (new MathematicalText("ABC"))->overbar();

    $mathParagraph->add(new MathBlock($overbar));

    $presentation->save("overbar.pptx", SaveFormat::Pptx);
} finally {
    if (!java_is_null($presentation)) {
        $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.
