USING THE ORDER OF OPERATIONS WORKSHEET

1. Evaluate the given expression for x = 7.

4(x - 4)

2. Evaluate the given expression for x = 7.

4x - 4

3. Evaluate the given expression for w = 6,x = 5 and y = 3.

w - x + y

4. Evaluate the given expression for x = 9.

x² - x

5. Evaluate the given expression for x = 3  and y = 5.

3x + 2y

6. Evaluate the given expression for s = 5.

s² + 7s - 2

7. Evaluate the given expression for m = 5  and n = 2.

m² + 2mn²

8. Evaluate the given expression for m = 3.

(2m² + 5m - 7)/2

1. Answer :

4(x - 4)

Substitute x = 7.

= 4(7 - 4)

= 4(3)

= 12

2. Answer :

4x - 4

Substitute x = 7.

= 4(7) - 4

= 28 - 4

= 24

3. Answer :

w - x + y

Substitute w = 6, x = 5 and y = 3. 

= 6 - 5 + 3

= 1 + 3

= 4

4. Answer :

x² - x

Substitute x = 9.

= 9² - 9

= 81 - 9

= 72

5. Answer :

3x + 2y

Substitute x = 3 and y = 5.

= 3(3) + 2(5)

= 9 + 10

= 19

6. Answer :

s² + 7s - 2

Substitute s = 5.

= 5² + 7(5) - 2

= 25 + 7(5) - 2

= 60 - 2

= 58

7. Answer :

m² + 2mn²

Substitute m = 5 and n = 2.

= 5² + 2(5)(2)²

= 25 + 2(5)(4)

= 25 + 40

= 65

8. Answer :

(2m² + 5m - 7)/2

Substitute m = 3.

= [2(3)² + 5(3) - 7]/2

 = [2(9) + 5(3) - 7]/2

= [18 + 15 - 7]/2

= [33 - 7]/2

= 26/2

= 13
