e.(-4) - (+2) = ?
f.-9-(-5) = ?

Answer 1

1. -3

2. 9

3. 5

4. -12

2)

a 9-6=3

b.5-8=-3

c.-12-6=-18

d.10+8=18

e.+4-2=2

f.-9+5=-4

Answer 2

1.

a. -3

b. 9

c. 5

d. -12

2.

a. 9 + (–6) = 3

b. (–5) + 8 = 3

c. (–12) + (–6) = -18

d. 10 – (–8) = 18

e. (–4) – (+2) = -6

f. –9 – (–5) = 4

3.

a. 8 * 3 = 24

b. -7 * 5 = -35

c. -6 * -9 = 54

d. 8 / -2 = -4

e. -24 / -3 = 8

f. -36 / 6 = -6

4.

$65.00 - $82.00 = -$17

5.

$84

6.
