Which product is negative?

-2⋅ (-7) ⋅12⋅ (4)

-6⋅ (-7) ⋅ (-8) ⋅0

-3⋅ (-2) ⋅ (-4) ⋅ (-7)

4⋅ (-9) ⋅ (-3) ⋅ (-1)

4⋅ (-9) ⋅ (-3) ⋅ (-1) product is negative,

Step-by-step explanation:

Given : Numbers.

To find : Which product is negative.

Solution : We have given expression with positive sign and negative sign.

By the integer rule : When we multiplied the even number of negative it become positive.

Example: - a * - b = ab.

When we multiplied the odd number of negative it become negative.

Example: - a * - b * - c = - abc.

This expression have - 6⋅ (-7) ⋅ (-8) ⋅0 have 3 negative sign but it has 0 so, this expression would be zero.

Then only this 4⋅ (-9) ⋅ (-3) ⋅ (-1) expression have 3 negative sign

So, its product would be negative.

Therefore, 4⋅ (-9) ⋅ (-3) ⋅ (-1) product is negative,

The negative answer is the last one, 4⋅ (-9) ⋅ (-3) ⋅ (-1)

positive times a negative = a negative

negative times a negative = a positive

a positive times a negative = a negative
