Question

Resolva a expressão:
a) 22-8+{9*12+1: [8-(5:1+12*5:5)+7-9]}
b) 18*9+(23*59-12:6)
c) 31*4:6+(-12.4+-5.-2+5) :-2

Answer 1

a) 22-8+{9*12+1: [8-(5:1+12*5:5)+7-9]}

22-8+{9*12+1 : [8-(5+12*1)+7-9]}

22-8+{9*12+1 : [8-17-2]}

22-8+{9*12+1: -11}

22-8+{108+1: -11}

22-8+9,9090

14+9,9090

23,909

b) 18*9+(23*59-12:6)

18*9+(1357-2)

18*9+1355

162 + 1355

1517

c) 31*4:6+(-12.4+-5.-2+5) :-2

31*4:6+(-48+10+5) : -2

31*4:6-33:-2

124:6-33:-2

20,66+16,50

37,16
