Question

Si: A = – (–9) + (–3) – (–2) – (+13) B = + (–12) – [+3 – (+7) + (–2)] Calcular: A – B​

Answer 1

Respuesta:

1

Explicación paso a paso:

A = +9 -3 +2 -13

       9 + 2 - 3 - 13

           11 - 16

             -5

B = -12 - [ 3 - 7 - 2 ]

      -12 - [ 3 - 9 ]

         -12 - [ - 6 ]

           -12 + 6

                -6

A - B = -5 - (-6) = -5 + 6 = 1
