a) 25-(13+16) = 25 -29 = -4
b)32 -(-5+10) = 32 - 5 =27
c)14 + (-17+4) = 14 -13 = 1
d) -42-(56-60) = -42 - (-4) = -42 + 4 = -38
e)-21-(16-12) = -21 - 4 = -25
f)-17 + (-5+10) = -17 + 5 = -12
g)(6-10)-(12+15)=-4-27=-31
25 -(13+16) = 25 -29 = - 4
32-(-5+10) = 32 -5 = 27
14+(-17+4)= 14 - 13 = 1
-42 -(56-60) = - 42 -(-4) = -42 + 4 = - 38
- 21 -(16 -12) = -21 -(4)= - 21 -4 = - 25
-17+(-5+10) = -17 +(5)= -17 + 5 = - 12
(6-10) - (12+15) = -4 -(27) = - 4 - 27 = - 31
