Question

(-7)*(-2)+(-4)/(-2-2)
(-7+6)*(-2+5)
(-3)*(-5)-(-4)*(-6)
(-50)/(-10)-(-4-5)
(-7)*(-6)/(-10+8)
[ (-3)*(-7)+(-2+9]

Answer 1

Respuesta:

$( - 7) \times ( - 2) + ( - 4) \div ( - 2 - 2) \\ 14 + ( - 4) \div ( - 4) \\ 14 + 1 = 15 \\ \\ ( - 7 + 6) \times ( - 2 + 5) \\ - 1 \times 3 = - 3$

Explicación paso a paso:

$( - 3) \times ( - 5) - ( - 4) \times ( - 6) \\ 15 - 24 = - 9 \\ \\ ( - 50) \div ( - 10) - ( - 4 - 5) \\ 5 - ( - 9) \\ 5 + 9 = 14$

$( - 7) \times ( - 6) \div ( - 10 + 8) \\ 42 \div ( - 2) = - 21$

[ (-3)*(-7)+(-2+9]

21+7=28
