Question

6. Simplify:
(i) (-8) 9+(-8) X 7
(iii) 20 (-16) +2014
(v) (-11) (-15) + (-11) (-25)
(vii) (-16)(-8) + (-4) (-8)​

Answer 1

Answer:

(8) 9+ -(8)×7

8+9-8×7

17- 56

-39

Answer 2

Answer:

1. (-8) 9+(-8) ×7

= −72−8×7

= −72−56

= -128

3. 20 (-16) + 2014

= 320 + 2014

= 1694

5. (-11) (-15) + (-11) (-25)

= 165−11×−25

= 165 - (-275)

= 165 + 275

= 440

7. (-16) (-8) + (-4) (-8)

= 128 - 4 × -8

= 128 - (-32)

=128 + 32

= 160
