Reverse thinking

Factoring illustrates "reverse thinking" common in mathematics. In our everyday lives, we illustrate this type of thinking often. If I know in 15 years that I may have to send a child to college, then knowing the end result (price of college) I must think in reverse and figure out steps I must take to lead up to the final outc
