Question

cuanto es 15-(7-9)*6+8*(-2)
6*(-4)-[5-(12 - 9)]
45/(-8+3)*2-10
20 *(-2)/5-16/8*(-3)

Answer 1

Respuesta:

$15 - (7 - 9) \times 6 + 8 \times ( - 2) \\ 15 - ( - 2) \times 6 + ( - 16) \\ 15 - ( - 12) - 16 \\ 15 + 12 - 16 = 11$

$6 \times ( - 4) - ((5 - (12 - 9))\\ - 24 - (5 - (3) \\ - 24 - 2 = - 26$

$45 \div ( - 8 + 3) \times 2 - 10 \\ 45 \div ( - 5) \times 2 - 10 \\ - 9 \times 2 - 10 \\ - 18 - 10 = - 28$

$20 \times ( - 2) \div 5 - 2 \times ( - 3) \\ - 40 \div 5 + 6 \\ - 9 + 6 = - 3$
