Knowing Numbers

"One aim of algebra is to provide a compact, symbolic description of the world."

- Robert Blitzer, mathematician

Terminology:

variable - the unknown value (or number)

Hello everyone!

Here is a simple but useful math fact.

One basic rule of math that is good for all to remember whether we are balancing our

checkbook or helping with math homework is how to commute numbers.

Remember : for any two variables (including 0),

A + B = B + A

Translation: If 1 + 2 = 3, then 2 +1 = 3
