a) 30+[-16+7-10]
30+[-26+7]
30+[-19]
30-19= 11
b)-10-[11+(-16)+1]
-10-[11-16+1]
-10-[-4]
-10+4=-6
c)18-(29-[13-(-5)]
18-29-[13+5]
-11-18=-29
d)-22-[29+(4-26)-28]
-22-[29+(-22)-28]
-22-[7-28]
-22-[-21]
-22+21= -1
e)-7-[-(6)+11-(-13+9)-4]
-7-[-6+11+13+9-4]
-7+6+24+5
-7+35= 28
f)9+10+21-(-26+25)+18
19+21+26+25+18= 109
g)11+[-17+22+16-29]+46+54
11+[-8]+100
11-8+100= 103
h)36-{14+[57-(-32)]}
36-{14+[57+32]}
36-14+89
22+89=111
