Question

Resolva as expressões numéricas abalxo:
1 )7- (1+3)=
2 )9-(5-1+5)=
3 )10-(2+5)+4=
4 ) (13-7)+8-1=
5 )15-(3+2)-6=
6 )25-[10+(7-4)]=
7 )32+{10-(9-4)+8}=
8)45-{12-4+(2+1)}=
9) (10-4)-(9-8)+3=
10)50-{37-(15-8)}=
11)28+{50-(24-2)-10}=
12)20+{13+(10-6)+4}=
13)52-{12+[15-(8-4)]}=
14)25+{12+[2-(8-6)+2]}=
15) {[(18-3)+(7+5)-2]+5}-12=
16)65-{30-[20-(10-1+6)+1]}=
17)45+{15-[(10-8)+(7-4)-3]-4}=
18)40+{50-[35-(25+5)-1]}+7=
19)38-{20-[22-(5+3)+(7-4+1)]}=
