You'll use the on-screen keyboard to create new expressions. Open the keyboard by opening the insert menu in the toolbar and choosing "math expression"
Your new expression will be shown in the top white bar of the keyboard.
On the left we have our basic calculator functions, so I can create "4 divided by 2."
We can escape from any sub-expression by hitting the right-arrow key or spacebar, so let's get out of that fraction.
The comma in the third row of the middle section is for making tuples, which we'll talk about in a different video.
We support subscripts, which is the "x-sub-n" button. Above that is the absolute value button.
In our third section we have powers, roots, and logarithms.
Below that we have placeholders, which we'll also cover in a different video.
We have the "long var," which you can use to enter a variable name that's longer than one letter.
There are two mode buttons at the top right: "abc" for a more standard english keyboard, and "alpha-beta-gamma" for all your greek letters.
There's the shift key here if you want to access capitals.
One last thing, if you see a key with a "..." indicator, hold onto it to open a sub-menu with related symbols.
If you want your relational operators, use the equals sign sub-menu.
Click "Done" to put the expression on the canvas.
