Tell me what you know about Order of operations

I've got it.

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

I Dont Understand. I need help.

I've got it! I can teach

4+3=7

Combine Values to find a total

4 - 3=1

Finding the difference between values

4×3=12 or 4+4+4=12

Serial addition

Splitting number into equal parts

12÷3=4

Review

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

Did you get 7? or Did you get 9?

Division First

Addition First

4 + 10 ÷ 2 14 ÷ 2 7

4 + 10 ÷ 2 4 + 5 9

Write an awesome subtitle here to provide context

Both of these anwsers can't be right

Do you know Dear Aunt Sally ?

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)

Rules states to always do what is inside of them first

Next

Exponents

Exponents are just repeated multiplication

4² = 4 × 4 =16

4³ = 4 × 4 × 4 =64

Then

Multiplication and Division (from left to right)

Last

Addition and subtraction (from left to right)

4² + 5 × (1+3) ÷ 2 - 1

(5 + 4) ÷ 3

1. Parentheses (5+4)=9
2. No exponents
3. No multiplication
4. Division 9÷3=3
5. No addition
6. No subtraction

Write an awesome subtitle

(5+4)÷3=3

Practice

(1×3)²-5=

1. Parentheses (1×3)=3
2. Exponents 3²=9
3. No multiplication
4. No Division
5. No addition
6. Subtraction 9-5=4

Write an awesome subtitle

(1×3)²-5 = 4

Practice

4×5-12÷4=

1. No Parentheses
2. No Exponents
3. Multiplication 4×5=20
4. Division 12÷4=3
5. No addition
6. Subtraction 20-3=17

Write an awesome subtitle

4×5-12÷4=17

4² + 5 × (1+3) ÷ 2 - 1

Parentheses 4² + 5 × (1+3) ÷ 2 - 1

Exponents 4² + 5 × 4 ÷ 2 - 1

Multiplication 16 + 5 × 4 ÷ 2 - 1

Division 16 + 20 ÷ 2 - 1

Addition 16 + 10 - 1

Subtraction 26 - 1

25

4² + 5 × (1+3) ÷ 2 - 1=25
