One factor is -7 and the product is 56. Enter the other factor.
پاسخ درست
-8
توضیح
The product lies above zero while the known factor lies below it, so the missing factor must lie below zero as well for the two reversals to cancel, and 7 times 8 is 56. Reporting 8 gets the size right but would produce a product 56 units below zero instead.
