Answer 1

a) 13x3+2x3+5=
39+6+5=
45+5=50

b) (7+2) x (3-1) =
9x2=18

c) (4+2x5)-3=
(4+10)-3=
14-3=11

d) [(4+16x2)x5-10] =
[(4x32)x5-10] =
[128x5-10] =
[640-10] =630

e) {10+[5x(4+2x5)-8]x2}-100=
{10+ [5x (4+10)-8] x2}-100=
{10+ [5x14-8] x2}-100=
{10+ [70-8] x2}-100=
{10+62x2}-100=
{10+124}-100=
134-100=34

Espero ter ajudado XD
