The Order of Operations

2
Consider the expression, 2 + 5 x 4 Consider the expression, 2 + 5 x 4

3
The Order of Operations Consider the expression, 2 + 5 x 4 Consider the expression, 2 + 5 x 4 Evaluate the expression by doing the multiplication first. Evaluate the expression by doing the multiplication first.

4
The Order of Operations Consider the expression, 2 + 5 x 4 Consider the expression, 2 + 5 x 4 Evaluate the expression by doing the multiplication first. Evaluate the expression by doing the multiplication first. 2 + 5 x 4 =2 + 20 = 22

5
The Order of Operations Consider the expression, 2 + 5 x 4 Consider the expression, 2 + 5 x 4 Evaluate the expression by doing the multiplication first. Evaluate the expression by doing the multiplication first. 2 + 5 x 4 =2 + 20 = 22 Evaluate the expression by doing the addition first.

6
The Order of Operations Consider the expression, 2 + 5 x 4 Consider the expression, 2 + 5 x 4 Evaluate the expression by doing the multiplication first. Evaluate the expression by doing the multiplication first. 2 + 5 x 4 =2 + 20 = 22 Evaluate the expression by doing the addition first. 2 + 5 x 4 =7 x 4 = 28

7
The Order of Operations Consider the expression, 2 + 5 x 4 Consider the expression, 2 + 5 x 4 Evaluate the expression by doing the multiplication first. Evaluate the expression by doing the multiplication first. 2 + 5 x 4 =2 + 20 = 22 Evaluate the expression by doing the addition first. 2 + 5 x 4 =7 x 4 = 28 We need rules!

The Order of Operations BEDMAS

9
The Order of Operations BEDMAS B E DM AS

10
The Order of Operations BEDMAS B- Do operations in brackets first. E DM AS

11
The Order of Operations BEDMAS B- Do operations in brackets first. E- Evaluate exponents next. DM AS

12
The Order of Operations BEDMAS B- Do operations in brackets first. E- Evaluate exponents next. DM- Do dividing and multiplying in the order they appear. AS

13
The Order of Operations BEDMAS B- Do operations in brackets first. E- Evaluate exponents next. DM- Do dividing and multiplying in the order they appear. AS- Do adding and subtracting in the order they appear.

14
The Order of Operations BEDMAS Ex) 5 x 6 – 4 ÷ 2 = 30 – 2 = 28

15
The Order of Operations BEDMAS Ex) 4 x 12 ÷ 3 x 2 – (9 + 4) = 4 x 12 ÷ 3 x 2 – 13 = 48 ÷ 3 x 2 – 13 = 16 x 2 – 13 = 32 – 13 = 19

16
The Order of Operations BEDMAS Ex) (4 + 3 2 – 2 3 ) 2

17
The Order of Operations BEDMAS Ex) (4 + 3 2 – 2 3 ) 2 = (4 + 3x3 – 2x2x2) 2

18
The Order of Operations BEDMAS Ex) (4 + 3 2 – 2 3 ) 2 = (4 + 3x3 – 2x2x2) 2 = (4 + 9 – 8) 2

19
The Order of Operations BEDMAS Ex) (4 + 3 2 – 2 3 ) 2 = (4 + 3x3 – 2x2x2) 2 = (4 + 9 – 8) 2 = 5 2

20
The Order of Operations BEDMAS Ex) (4 + 3 2 – 2 3 ) 2 = (4 + 3x3 – 2x2x2) 2 = (4 + 9 – 8) 2 = 5 2 = 25
