The value of the answer is the sum of the absolute values of the numbers and the sign of the answer is the same as that of the two numbers.
The sum of a set of addends whose sign is the same is the sum of the absolute values of the addends with the same sign as the addends.
Do the addition. Keep the sign.
The sign doesn't change.
Here is the rule you need to know: Addition: If the signs are the same, add them up and keep the sign. (e.g. -5+ -9= -14) If the signs are opposite, find the difference between the two numbers and keep the sign of the greater number. (e.g. 5+ -9= -4)
