Question

What will be the sign of the product is we multiply together

$8$ negative integers and $1$positive integer?

Answer 1

If negative integer appears even number of times in a product, the final answer is positive. Hence, If we multiply $8$negative integers we get a positive integer

Now multiplying a positive integer by $1$positive integer, we get a positive integer.

$\left[\left(+\right)\times \left(+\right)=\left(+\right)\right]$

Hence, if we multiply together $8$ negative integers and $1$positive integer, the sign of the product will be positive.
