Explicação passo-a-passo:

8:4+(4-16:8)2+(10:5+45:9)

2+(2)2+(7)

2+4+7 13

[(64:8-19:19)2+50:25]-(3.5-7.2)

[(8-1)2+2]-(15-14)

[(7)4]-(1) [28]-1 28-1 27

[54:9+(5.4+6.5-4.3)]-20:10

[6+(20+30-12)]-2

[6+(38)]-2 [6+38]-2 [44]-2 44-2 42

[10+6.4+(15:3+21:7)2]-5.10

[10+24+(5+3)2]-50

[34+(8)2]-50

[34+16]-50 [50]-50 50-50 0
