The product of -90 integers x 9 integers = - 810 integers. So the answer is positive integer. Because the negative integers on multiplication become positive so the end result will also be positive.

Negative x negative = positive in mathematical multiplication which is known by all. On applying such rule, you are sure to get positive value in the end result of multiplication.

Product of 90 negative integers and 9 positive integers will get positive sign

Step-by-step explanation:

General rule for product of different signs:

Positive × Positive = Positive

Negative × Negative = Positive

Positive × Negative = Negative

Negative × Positive = Negative

From the above rule, it is clear that:

If you multiply even number of negative values, it will become positive value.

If you multiply odd number of negative values, it will become negative value.

Here 90 is the even number.

So that product of 90 negative integers become positive value.

Multiplying 2 positive integers, it will remain positive integers.

So that product of 9 positive integers remain positive value.

Therefore, 90 negative integer and 9 positive integer are positive.

From the above rule, if you multiply two positive integers it gives a positive value only.

Hence product of 90 negative integers and 9 positive integers will get positive sign.
