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.
