Website on adding positive and negative numbers http://www.mathsisfun.com/positive-negative-integers.html The rule for adding positive and negative numbers is adding positives is just simple addition.If you have a positive and negative number like What is 6 + (-3) ? or what is 6 - (+3) ? They are both the same. They are both subtraction. If you don't understand you could always use a number line like this =Using The Number Line= You can use the [|Number Line] to help you to **add**: And **subtract**:

 * ===6 - 5 = 1=== ||

It is also great to help you with **negative numbers**:

__**Subtracting Positive and Negative Integers**__
by: Tajh

To subtract integers, change the sign on the integer that is to be subtracted.

Example: 14 - (-6) =14 + 6= 20 Example: -14 - (+6) =-14 - 6= -20 Example: 14 - (+6) =14 - 6= 8 Example: -14 - (-6) =-14 + 6= -8
 * If both signs are positive, the answer will be positive.
 * If both signs are negative, the answer will be negative.
 * If the signs are different subtract the smaller absolute value from the larger absolute value. The sign will be the sign of the integer that produced the larger absolute value.
