It is positive.
-- Their sum and difference both have the same sign that the two integers have. -- Their product and quotient are both positive.
the sum of 2021 nonnegative integers is 2020. what is the product of the numbers
The sign of the product of four integers depends on the signs of the individual integers. There are 4 cases: 1) When all 4 integers share the same sign and all are non-zero (either all are positive or all are negative), the product is positive. 2) When 3 of the 4 integers share the same sign and all are non-zero (3 are positive and 1 is negative; or 3 are negative and 1 is positive), the product is negative. 3) When 2 of the integers are positive non-zero and the other 2 of the integers are negative non-zero, the product is positive. 4) If even one of the integers is zero, the product is zero (no sign - it is neither positive nor negative).
The product of 2 (or more) positives is positive. The product of 2 negatives is positive. So product of 6 negatives = 3*(product of two negatives) = product of 3 positives = positive. So overall sign is positive.
The product of three positive numbers is positive. The product of three negative numbers is negative.
The product of two integers will be: * Zero, if one factor, or both, are zero. * Positive, if both factors have the same sign (both positive, or both negative) * Negative, if the two factors have different signs. Actually, these rules apply to all real numbers, not just to integers.
You get a product which is positive.
negative x negative = positive
