Answer 1

A) {[(2^3.4+3)/7+(3+15/5) .3] .2 - (19 - 7)/6}.2+12

{[(8.4+3)/7+(3+3).3].2-(12)/6}.2 +12

{[(35)/7+(6).3].2-2}.2+12

{[5 + 18].2-2}.2+12

{[23].2-2}.2+12

{46-2}.2 +12

44 . 2 +12

88+12

100

B) -8+{-5+[(23-12)+(13+12)]-10}

-8+{-5+[11+25]-10}

-8+{-5+36-10}

-8+21

13

C){[(4^2+2)+3.2]/8+5.3}/10

{[(16+2)+6]/8+15}/10

{[(18)+6]/8+15}/10

{24/8+15}/10

{3+15}/10

{18}/10
