Unit 1--Order of Operations
Common Core Math Standards
- 5.OA.1 – Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.
- 5.OA.2 – Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. For example, express the calculation “add 8 and 7, then multiply by 2” as 2 × (8 + 7). Recognize that 3 × (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum or product.
Order of Operations
Do you see a long equation and you can't remember what to do? Well, check out the song below and learn it (at least learn the chorus). Whenever you are working on a long equation, this song will pop into your mind and you'll know just what to do.
In the short video below I'll explain the problems that many students encounter when working on Order of Operations. The first test covers the order of operations. You can find the study guide linked below. The review video can be seen below.
What are the Order of Operations?
When solving a math equation you solve each step in the following order:
Parenthesis--Solve everything inside of the parenthesis first.
Exponents--Solve the exponents second.
Multiplication & Division--Solve all of the multiplication and division in order from left to right.
Addition & Subtractions--Solve all of the addition and subtraction in order from left to right.
