How To Write Math Equations In Google Slides: A Comprehensive Guide

Google Slides is a powerful tool for creating presentations, and it’s used by everyone from students to seasoned professionals. But what if you need to incorporate complex mathematical equations? While Google Slides isn’t primarily a math editor, it does offer several methods to seamlessly integrate equations into your presentations. This guide will walk you through everything you need to know about how to write math equations in Google Slides, ensuring your presentations are both visually appealing and mathematically accurate.

1. The Simplest Solution: Using the Equation Editor in Google Docs (and Copying!)

Let’s start with the most accessible approach. Google Docs has a built-in equation editor, and leveraging it is often the quickest way to get your equations into Slides.

Here’s the breakdown:

  1. Open Google Docs: Create a new document or open an existing one in Google Docs.
  2. Insert Your Equation: Go to “Insert” > “Equation.” This will open the equation editor.
  3. Build Your Equation: Use the equation editor’s toolbar to construct your mathematical expression. You’ll find symbols for fractions, exponents, radicals, integrals, and much more. Practice with the editor. The more you use it, the more you’ll get used to it.
  4. Copy the Equation: Once your equation is complete, select it and copy it (Ctrl+C or Cmd+C).
  5. Paste into Google Slides: Go to your Google Slides presentation and paste the equation (Ctrl+V or Cmd+V) into the desired slide.
  6. Resize and Position: Adjust the size and position of the equation as needed to fit your presentation layout.

This method is ideal for quick equation insertions and offers a user-friendly interface. However, you’re essentially pasting an image, so you won’t be able to edit the equation directly within Google Slides. If you need to make changes, you’ll have to go back to Docs, edit, copy, and paste again.
