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.

Example: (a+b)(a+b) = a2 + 2ab + b2
