How could you change the expression
(-) so that the product is
positive?

You make one number positive.

Step-by-step explanation:

A negative number multiplied by a negative number is positive, so that means that if you choose two of the numbers in this expression you will get a positive number. However, there is still one negative number left and you will get a negative product if you multiply, because a positive number multiplied by a negative number is a negative number. If you make this last number positive you will get a positive product.

Hope this helps!
