Answer 2

Answer:

(-1) × (-1) × (-1) ×             10 times is equal to (1).

Step-by-step explanation:

Explanation:

Given in the question,

(-1) × (-1) × (-1) ×             10 times

• Positive Integers have values higher than zero. Integers with negative values are less than zero. Zero has no positive or bad aspects.

• Product of a positive integer and a negative integer is negative.

• Product of a positive integer and a positive integer is positive.

• Product of two negative integers is negative.

And we also know that the only thing that alters when we multiply a number by (-1) is its sign. In other words, if the number was positive, it now has a negative value. Additionally, if the initial value was negative, it turns positive.

Step 1:

From the question we have,

(-1)×(-1)×(-1)×(-1)×(-1)×(-1)×(-1)×(-1)×(-1)×(-1)

⇒ (-1)×(-1)×(-1)×(-1)×(-1)×(-1)×(-1)×(-1)× (1)   [where '-' ×'-' = +]

⇒ (-1)×(-1)×(-1)×(-1)×(-1)×(-1)×(-1)×(-1)        [where '-' ×'+' = -]

⇒ (-1)×(-1)×(-1)×(-1)×(-1)×(-1)×(1)

⇒ (-1)×(-1)×(-1)×(-1)×(-1)×(-1)

⇒ (-1)×(-1)×(-1)×(-1)×(1)

⇒ (-1)×(-1)×(-1)×(-1)

⇒ (-1)×(-1)×(1)

⇒(-1)×(-1) = 1

Final answer:

Hence, (-1) × (-1) × (-1) ×             10 times is equal to (1).
