3. Single Variables
In Algebra we learn that no symbol between variables (letters) means multiplication. The ClassPad also thinks this way when we use its single variables (bolder letters). Sometimes, however, we want to define a variable with more than one letter. For example, let width = length – 12. To do this, we can use letters from the regular keyboard.
