Answer 1

Resposta:

a) 5+(3-1)= 7

b) (13-4)-8= 1

c) 12-(7-3)= -8

d) (20-3)+(7+5)= 29

e) 5- (3+(2-5))= 1

f) 3-(5-(4-6))= -6

g) 2+(8-(7-5)+3)= 11

   

h) -8+(4-(7-13)-1) +5= 2

i) 1-(5+(1-9)= 12

j) -13-(10-(7+5)= -11

k) -35+(18-33)-(55 +8)= -43

1) 23-(-19+32)-(8-27)+(12-21)= 0

m) (13-7)+(12+14)-(34-55) =​ -66
