That's where teacher John McGowan comes to the rescue with his new Google add-on called g(math).
This cool little equation editor that allows you to bust out math equations faster than Google Drive's built-in equation editor.
To get you up and going, I'm going to provide a written and video tutorial to guide you through the process.
Written Guide: Part 1 - Creating an Equation
Step 1: Open a document yo!
Step 2: Select the "Add-ons" menu and click "Get add-ons"
Step 3: Search for "math" in the search bar and click on "g(math)" to install.
Step 4: After it is installed, click on the "Add-ons" menu again and select "Create math expressions".
Step 5: A sidebar will open up to the right. Click on a prebuilt function, or if you want to get really geeky, then you can learn LaTex.
Step 6: Change the constants and coefficients of the equation and then click "Insert".
Step 1: Adding a graph is similar to adding an equation. After you install g(math), choose "Create a graph" from the "Add-ons" menu.
Step 2: Type in your equation into the field provided. You can also put in a second equation if you have a system of equations.
Note: If you need help with what to type to make a multiplication sign or any other math operator, then you can go here.
