### 4: How To Insert Math Equations in PowerPoint

If you are a Mathematician or a training course developer for Math related subjects PowerPoint 2013 offers wonderful options to insert Math equations on your slides. In this article, we will explore the options in detail.

**Inserting a Math Equation:**

To insert an equation you need to first insert a text box. Then go to the ‘Insert’ tab in PowerPoint and click on the drop down menu under ‘Equation’. This will open up a set of readymade equations as follows:

You can click on any of these equations to insert them in the text box. For example, you can insert the equation for ‘Expansion of a sum’ as follows:

You can always replace any part of the equation with your own numbers by clicking on the text. If you don’t need any of the preset equations given in the list, you can create your own equation by going to ‘Insert New Equation’ option.

You get a new tab in PowerPoint ribbon as shown below:

In the ‘Symbols’ group you get a whole lot of Math symbols to insert in your equation.

Apart from Basic Math symbols you can include Operators, Arrows or even Geometry in your equations.

**Inserting Fractions and Scripts:**

PowerPoint allows you to insert Fractions, Scripts etc. using simple number placeholders as shown below:

You can also include Scripts, Radicals, Integrals, Matrices, Trigonometric functions etc. using the same principle of number placeholders.

**Overcoming the issue of rendering:**

If you want to convert your slides to Flash or any other program, you might find some issues in rendering of the symbols correctly. A simple way to overcome the issue is – once you finish constructing the equation, ‘cut’ the text box that has the formula and ‘paste’ it back as a picture.

You might also choose to keep the original formula on the slide, hidden from view using ‘Selection pane’.

**Note**: You can find out more about the Selection Pane and how to use it in this tutorial.

**Understanding the difference between Professional and Linear layout of equations:**

PowerPoint allows you to write your equations either in Professional layout or in a linear layout. You can see the difference between the two layouts here:

The only reason why you may want to opt for ‘Linear layout’ for the equation is to save line space on a slide. However, if you want to preserve clarity of the equation structure, it is a good idea to settle for the default ‘Professional layout’.
