Mnemonics for Learning Algebra Concepts

Do you have a teen who is learning Algebra?

Some concepts and procedures such as keeping the signs straight when multiplying positive and negative numbers or factoring binomials can be challenging to remember.

I have two mnemonics you can share with your teen that will help her remember those processes.

Here they are.

Mnemonics for Learning Algebra

Multiplying Positive and Negative Numbers

Here’s a little mnemonic from Education World that will help teens know whether an answer should be positive or negative when multiplying numbers.

A good thing happening to a good person is good. (positive x positive = positive)
A good thing happening to a bad person is bad. (positive x negative = negative)
A bad thing happening to a good person is bad. (negative x positive = negative)
A bad thing happening to a bad person is good. (negative x negative = positive)

Factoring Binomials

Here’s an oldie but goodie for remembering the procedure for factoring binomials.

FOIL

First
Outer
Inner
Last

Example: (a+b)(a+b) = a² + 2ab + b²
