Pre Algebra

We are going to begin looking at Algebra. Algebra is a way of dealing with
unknowns that helps us find the unknown. It uses letters to take the place
of the unknown.
Therefore if we say that 3 more than something is equal to 15. This must
also mean that 3 less than 15 would equal our unknown.
So we could write this as:

X + 3 = 15 but we could also write it as X =15 - 3
