---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---| -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9

a). + 6 - 8 =

b). - 4 + 5 =

c). + 8 - 8 =

d). + 9 - 15 =

e). - 4 - 3 =

f). + 2 + 6 =

g). 0 - 5 =

h). - 2 - 5 =

i). - 1 + 0 =

2). (1 point each) Evaluate these expressions for:

a = 9 b = 4 c = 2:

a). a + b =

b). a - b =

c). b - a =

d). 2a + b =

e). 2b - c =

f). bc =

g). b/c =

h). ca - b =

i). cab =

a). + 6 - 8 =	b). - 4 + 5 =	c). + 8 - 8 =
