Question

A) 12+[35-(10+2)+27=

b) 60÷{-7+18÷(-3+12)}}-{7 (-3)-18÷(-2)+1]=

C) -8+{-5+[(8-12)+(13+12)]-10}=​

Answer 1

k) [-1 +(22-5x6)] ÷ (-5 +2) +1

[-1+(22-30)] ÷ (-3) +1

[-1-8] ÷ (-3+1

9÷(-3) +1

-3+1= -2

N) {[(8x4+3) ÷7 + (3+15÷ 5) x2- (19-7) ÷ 6} x2+12

{[35÷7+6x3] x2-(-12) ÷6 } x2+12

{[5+18] x2 -12÷6} x2+12

{ 23x2-12÷6} x2+12

{ 46-2} x2+12

44x2+12

88+12 =100

H) 37+[25-(11+19-4)]

37+[25-(30-4)]

37+[25-(+26)]

37+(25-26)]  

37+[-1]

37-1
