Question

A)-3[4(3-2) - (-5+16)+12]-16 B) 5-2.[(5-7)+(3-2)-1] .(-1) C) 1-8.[10. (-15-2)-17]+6.(-7-84) D)5-2. (3-11) . (-4) [5-(6-9)]

Answer 1

a) -3(4-11+12)-16 = -15-16 = -31
B) 5-2(-2+1-1)(-1)  = 5- 4  = 1
C) 1-8(10(-17)-17)+6(-91)  = 1-8(-187)-546 = 1+1496-546 = 951
D) 5-2(-8)(-4)(5-(-3))= 5-2(32)(8)= 5-512 = -507
