Answer:

1. 2(1)+2-3

=2+2-3

=4-3

= 1

2.4(-3)+3(-2)

= -12 + 1

= - 11

3.5(1)(2)

= 10

4.7(-2) + 2(2)

= - 14 + 4

= - 10

5. (-2)(-1) + (1)(2)

= 2 + 2

= 4

6. 2(2) / 4(-2)

= 4 / - 8

= 1/-8

7. 3(3) - 5(-1³)

= 9 - (-5) (apply kcc) law of subtracting a integer;)

= 9 + 5 (after applying kcc)

= 14

8. (-3)(-2)(-1)

= - 6

9.(1)(2)+(-2²)

= 2 + 4

= 6

10. 8(1)(2)+3(3)(2)-12

= 16 + 18 - 12

= 22
