Question

a) 6 : ( -8+5) =
b) (3 + 5) : (-2) =
c) (7 – 10) . ( -1-2) =
d) -2 . ( -5 +4 ) =
e) (100 – 30) : ( -3-4) =
f) (-11 -9 ) : ( -3+1)

Answer 1

a) 6 : (-8+5) =

6 : (-3) =

- (6:3) = -2

b) (3+5) : (-2) =

8 : (-2) =

- (8:2) = -4

c) (7-10) . (-1-2) =

-3 . (-3) =

3 . 3 = 9

d) -2 . (-5-4) =

-2 . (-9) =

2 . 9 = 18

e) (100-30) : (-3-4) =

70 : (-7) =

- (70:7) = -10

f) (-11-9) : (-3+1) =

-20 : (-2) =

20 : 2 = 10
