Best Answer

The sum of two positive numbers is always positive, and the sum of two negatives is always negative. If you have a positive and a negative number, there sum can be either, so look at the absolute values to decide. For example -3+2=-1. Since all you care about is the sign, look at the absolute value. If the negative number has a greater absolute value, the sum is negative and if the positive number's absolute value, which is the number itself, is bigger, the sum is positive. If the absolute values are equal, the sum is 0.

The sum of two negative numbers is positive and the sum of two negatives is negative. If you have both positive and negative numbers the sum can be either so look at the absolute value. If the negative number has a greater absolute value, the sum is negative. If the positive number has a greater absolute value the sum is positive. If the absolute values are equal, the sum is zero.

You can do this by inspection. If the second number is smaller than the first, their difference is positive. If the second number is greater than the first, then their difference is negative. If the second number is the same as the first number, then their difference is zero.

No. The product of two opposite numbers is always negative. Negative x positive = negative and Positive x negative = negative

any two negative numbers multiplied together equals a positive number. any two positives numbers multiplied together equal positive numbers and any negative and positive numbers multiplied together equals a negative.negative, negative = positivenegative, positive = negativepositive, positive = positive

Positive and negative whole numbers and zero are integers. Zero is neither negative or positive.
