Question

calcule as seguintes adições algebricas
a)3-{9-[-5+(10-18)+3]-10}
b)15-{10+[-8+(10-3)-7]+19}
c){25-[44+(60-78)-15]-33}
d){110-[-75+(19-23)-94]+10}

Answer 1

a)3-{9-[5+(-8)+3]-10}
   3-{9-[5-8+3]-10}
   3-{9-0-10}
   3-{-1}
   3+1
   4

b)15-{10+[-8+7-7]+19}
   15-{10+[-8]+19}
   15-{10-8+19}
   15-21
   -6

c){25-[44+(60-78)-15]-33}
   {25-[44+(-18)-15]-33}
   {25-[44-18-15]-33}
   {25-11-33}
   -19

d){110-[-75+(19-23)-94]+10}
   {110-[-75+(-4)-94]+10}
   {110-[-75-4-94]+10}
   {110-[-173]+10}
   {110+173+10}
   293
