Con cada paso porfa

Answer 1

{4 + [8 - (5 - 2) + (7 - 3)] + [- 3 -(- 8) +3]}

Restamos (5 -2) = 3

4 + (8 - 3) + (7 - 3)) + (- 3 -(- 8) + 3)

Restamos (7 - 3) = 4

4 + (8 - 3 + 4) + (- 3 -(- 8) + 3)

Removemos los polos opuestos (- 3, + 3)

4 + (8 - 3 + 4) - ( - 8)

Realizamos (8 - 3 + 4) = 9

4 + 9 - (- 8)

4 + 9 + 8 = 21
