Question

Explain how you can tell whether the sum of two integers is positive or negative, before adding them.

Answer 1

Explanation:

The sum will have the same sign as the integer with the greater magnitude.

Example: the sum of -11 and 5 is -6, where the 6 takes the sign of -11 (which has a greater magnitude than does 5).

Answer 2

The sum of any integer and its opposite is equal to zero. adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.
