Tell me what you know about Order of operations

I Dont Understand. I need help.

I think I've got it. I need a little help.

I've got it.

I've got it! I can teach

Splitting number into equal parts

Serial addition

Finding the difference between values

Combine Values to find a total

12÷3=4

4×3=12 or 4+4+4=12

4 - 3=1

4+3=7

Review

Can you solve the equation? 4 + 10 ÷ 2 =

Both of these anwsers can't be right

Did you get 7? or Did you get 9?

4 + 10 ÷ 2 4 + 5 9

4 + 10 ÷ 2 14 ÷ 2 7

Write an awesome subtitle here to provide context

Addition

First

Rules states to always do what is inside of them first

Parentheses

Parentheses and Brackets

Symbols that curves forwards and backwards

When you put numbers and operations inside of them they form a group

(3+4)

Next

4³ = 4 × 4 × 4 =64

Exponents

Exponents are just repeated multiplication

4² = 4 × 4 =16
