PLIS CON PROCEDIMIENTO

Answer 1

Explicación paso a paso:

4) – 8 + {[7 + (5 – 10)] + (25 – 13)}

– 8 + {[7 + ( - 5)] + (12)}

– 8 + {[7 - 5] + (12)}

– 8 + {2 + (12)}

-8 + 14

6

5) 6 + (7 – 9) + [( 3 – 11) + (– 24 + 18)]

6 + ( - 2) + [( -8) + (-6)]

6 + ( - 2) + [-8 - 6]

6 - 2 + [-14]

4 - 14
