Question

2. Resuelvan los siguiente cálculos e(100-30):(-4-3) f (-11-9):(-3+1)g (-2+3).(-5-4):(4-1)h(-10-4):(-6-1).(3-6)​

Answer 1

Respuesta:

$e)(100 - 30) \div ( - 4 - 3) = \\ 70 \div ( - 7) = \\ - 10$

$f)( - 11 - 9) \div ( - 3 + 1) = \\ - 20 \div ( - 2) = \\ 10$

$g)( - 2 + 3) \times ( - 5 - 4) \div (4 - 1) = \\ 1 \times ( - 9) \div 3 = \\ - 9 \div 3 = \\ - 3$

$h)( - 10 - 4) \div ( - 6 - 1) \times (3 - 6) = \\ - 14 \div ( - 7) \times ( - 3) = \\ 2 \times ( - 3) = \\ - 6$
