Question

a)18-(-8)•(+2) b)15+(-5)•(-4) c)24:(-4)-(-6) d)22-(-15):(-3)

Answer 1

a)18-(-8)x(+2)=
18+8x2=
18+16=
34

b)15+(-5)x(-4)=
15-5x(-4)=
15+20=
35

c)24:(-4)-(-6)=
-6+6=
0

d)22-(-15):(-3)=
22+15:(-3)=
22-5=
17

Answer 2

$18 - (-8) . (+2) = \\ 18 - (-16) = \\ 18 + 16 = \\ \fbox{34}$

$15 + (-5) . (-4) = \\ 15 + 20 = \\ \fbox{35}$

$24 : (-4) - (-6) = \\ (-6) - (-6) = \\ -6 + 6 = \\ \fbox{0}$

$22 - (-15) : (-3) = \\ 22 - (+5) = \\ 22 - 5 = \\ \fbox{17}$
