Answer 1

Explicación paso a paso:

Resuelve en tu cuaderno las siguientes operaciones.

(-9)(+5) = -45

(+15)(-7) = -105

(+15)(-14) =  -210

(-12)(-9)(+7) = 756

(-25)(+15)(-9) = 3375

(-12)(-4)(+5)(-8) = -1920

(-32)(-14)(-9) = -4032

(-11)(+6)(-3) = 198

(-15)(-16)(-13) = -3120

(+19)(-13)(-8)(-4) = -7904

(+9)(-5)(-7)(+8)(-9) = -22680

(-12)(+12)(-7) = 1008
