b)-(-3)+(-7-3)-(7-15)+(-8+2-5)
c)-16-(-8+3)+(-12-3)+(-7)-(-2-13)
d)4+(-6-3)-[-8+(-2+5)]
e)-(-12+8)+[-7+2+(8-15+3)-(-9+8-3)]
f)-16+{-10-[-4+(-3+5)]-3}-{4-[-6+(2-5)-7[+3}-9

Answer 1

a) =-8+8+3-7=-4
b) =3-10+8-11=-10
c) =-16+5+15+7+15=-18
d) =4-9+5=0
e) =4-2-4+4=2
f) =-16-10+2-3-(4-13)-9=-27+11-9=-25
