A better way to do it is to have the "Insert Equation" button as part of your toolbar. To add this button, right click on the toolbar, go down to "Customize ". A window will pop up.
In the "Commands" tab, under "Catagories", click on "Insert".
On the right side of the window, search for "Equation Editor". The button looks like a square root of alpha.
Left mouse click on the button and hold it down. Drag and drop where you want to put it in your toolbar.
Close Window.
When you want to use this button, go to where you want to insert your equation and just click on the button.
You'll probably find, like most people, the equation editor is not all that friendly. It's not easy to insert just anything. Another way of doing this is to only have superscripts and subscripts. You can add those buttons to your toolbar also, then for example, x squared is created by putting in x2, then highlighting the 2 and pressing the superscript button. You can add those to the toolbar by following the directions above and clicking on "Format" instead of "Insert". Superscript and Subscript buttons will then be in the right side of the window, and they can be dragged and dropped into the toolbar.
