1 The Order of Operations

2 Consider the expression, x 4 Consider the expression, x 4

3 The Order of Operations Consider the expression, x 4 Consider the expression, 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, x 4 Consider the expression, x 4 Evaluate the expression by doing the multiplication first. Evaluate the expression by doing the multiplication first x 4 = = 22

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

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

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

8 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) ( – 2 3 ) 2

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

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

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

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