Question

Обчисли(-28):(-4)-10;-65:13+90:(-15);(7-10)×(-18)+42:(-70);15-(4+8:(-2))-6.

Answer 1

$( - 28) \div ( - 4) - 10 = 7 - 10 = - 3$

$- 65 \div 13 + 90 \div ( - 15) = - 5 - 6 = - 11$

$(7 - 10) \times ( - 18) + 42 \div ( - 70) = - 3 \times ( - 18) - 0.6 = 54 - 0.6 = 53.4$

$15 - (4 + 8 \div ( - 2)) - 6 = 15 - (4 - 4) - 6 = 15 - 0 - 6 = 9$
