Caveman Chang CORRECTS Order of Operations (PEMDAS) with Aunt Sally

PEMDAS is a step-by-step guideline to help us solve problems and ensure there are no misunderstandings.This came from the idea that we are too lazy to put parentheses in their correct spot so we memorize an order of solving problems instead.

PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition and Subtraction. Multiplication and Division are on the same level so when they are together, solve the problem from left to right. Addition and Subtraction are also on the same level so when they are together, solve the problem from left to right.

When we are working with PEMDAS, we are going step-by-step only if possible. If the P E M D A S do not exist in the equation, skip over to the first operation that exists.

Practice Problems:
Level 1: Answer = 9
Level 2: Answer = 3
Level 3: Answer is (15 + 5 - 6 ÷ 3) x 0 = 0. Please note the answer may vary.
