Answer 2

Explicação passo-a-passo:

20+[18-(45-20-13)+9]=

20+[18-(25-13)+9]=

20+[18-(12)+9]=

20+[6+9]=

20+[15]=

35

80+{13-[(90+20-40)]+25=

80+{13-[(110-40)]+25=

80+{13-[70]+25=

80+{-57}+25=

23+25=

48

35-18+{110-[70+25-35+(18+7)]}=

35-18+{110-[95-35+(25)]}=

35-18+{110-[95-60]}=

35-18+{110-[35]}=

35-18+{75}=

35-93=
