Question

Describe order of operation and give an example

Answer 1

Order of Operation is commonly referred to as PEMDAS, an acronym for "Please excuse my dear aunt Sally," which references the order in which operations should  be calculated when solving a math problem.

P = parentheses

E = exponent

M = multiply

D = divide

A = add

S = subtract

So you don't always have all of these components, but you consider the ones present in the problem in front of you.    If there is no multiplication, but there is division and a set of parentheses, then you FIRST solve what's inside the parentheses, then  you divide.    If you have some examples, I'll show you.

Answer 2

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
Example is use Order of operations to solve 4•(5-3)+12
First you would do 5-3=2 than 2•4=8 than 12+8=20.
