More Math Techniques: PEMA pants

Well, Order of Operations is important in math. There is the default order and then there is the order cast by using symbols, such as parentheses. David is a visual learner, and pneumonics are helpful to him as well.

So on this particular Saturday we were working on this. It finally went well with this:



Parentheses
Exponents
Multiplication (he knows division is inverse multiplication)
Addition (ditto for subtraction)


which we remember by using the phrase "PEMA pants." [He is in Junior High, after all!!]
