Answer 1

Respuesta:

$a)3 \times ( - 8) \times ( - 2) = - 24 \times ( - 2) = 48$

$b) - 10 \times 2 \div ( - 5) = - 20 \div ( - 5) = 4$

$c) - 42 \div ( - 6) \times ( - 1) = 7 \times ( - 1) = - 7$

$d) - 4 \times ( - 2) \times ( - 5) = 8 \times ( - 5) = - 40$

$e) - 1 \times ( - 70) \div 35 = 70 \div 35 = 2$

$f) - 48 \div 8 \times ( - 1) = - 6 \times ( - 1) = 6$

$g) - 140 \div 5 \div ( - 7) = - 28 \div ( - 7) = 4$

$h) - 220 \div ( - 2) \times 3 = 110 \times 3 = 330$

$i)81 \div ( - 9) \div ( - 3) = - 9 \div ( - 3) = 3$

$j)38 \div 19 \times ( - 453) = 2 \times ( - 453) = - 906$
