Question

60/{2.[-7+18/(-6+12)]}-[7.(-3)-18/(-3)+1]

Answer 1

________________________________

60:{2.[-7+18:(-6+12)]}-[7.(-3)-18:(-3)+1]

60:{2.[-7+18:+6]}-[7.(-3)-18:(-3)+1]

60:{2.[-7+3]}-[7.(-3)-18:(-3)+1]

60:{2.-4}-[7.(-3)-18:(-3)+1]

60:8 -[7.(-3)-18:(-3)+1]

60:8 -[-21 +6+1]

60:8 -[-21 +7]

60:8 -[-14 ]

60:8 + 14

7,5 + 14

21,5

Answer 2

Explicação passo-a-passo:

60/{2.[-7+18/(-6+12)]} - [7.(-3) - 18/(-3) + 1] =

60/{2.[-7 + 18/6]} - [-21 + 6 + 1] =

60/{2.[-7 + 3]} - [-14] =

60/{2.[-4]} + 14 =

60/-8 + 14 =

-15/2 + 14 =

(-15 + 28)/2 =

13/2 = 6,5
