✔ 最佳答案
You multiply them together...-6 x 4 = -24 (because one negative and one positive is a negative)
-24 x -5 = 120 (because two negatives make a positive)

(-6)(4)(-5)
= (-6 * -5)(4)
= (30)(4)
= 120
= (-6 * -5)(4)
= (30)(4)
= 120

-6 * 4 = -24
-24 * -5 = 120
a negative * a negative = a positive
a positive * a negative = a negative
-24 * -5 = 120
a negative * a negative = a positive
a positive * a negative = a negative

-6 = (-1)(6)
-5 = (-1)(5)
(-6)(4)(-5) = (-1)(6)(4)(-1)(5)
= (-1)(-1)(6·4·5)
= (-1)(-1)120
= 120
-5 = (-1)(5)
(-6)(4)(-5) = (-1)(6)(4)(-1)(5)
= (-1)(-1)(6·4·5)
= (-1)(-1)120
= 120

if there is no sign, then it's multiplication. So the answer will be 120

(- 6) * 4 * (- 5) =
(- 1 * 6) * 4 * (- 1 * 5) =
(- 1) * (- 1) * 6 * 4 * 5 =
1 * 4 * 5 * 6 =
1 * 20 * 6 =
120
*******
(- 1 * 6) * 4 * (- 1 * 5) =
(- 1) * (- 1) * 6 * 4 * 5 =
1 * 4 * 5 * 6 =
1 * 20 * 6 =
120
