Add the numerals and keep the sign.


+9 + +3 = +12

-5 + -6 = -11

Just in case this is your next question: to add integers with different signs, subtract the numerals, and use the sign of the larger number.

When you add two integers how do you know if the answer is positive or negative?

-- If they both start out with the same sign (both negative or both positive), then do this: . . . . . add their two values . . . . . the answer has the same sign as the two original integers. -- If they start out with opposite signs (one negative and one positive), then do this: . . . . . forget about the signs . . . . . find their difference (subtract the smaller number from the larger one) . . . . . give it the sign of whichever original integer was the larger number.

Make the demoninators (bottom numbers) the same by multiplying the top and bottom of one (or both) fractions, then add them as you would with integers.

Why two negatives is a positive?

I feel that two negatives are positive because you add* your two negative integers* together, you would be doing this: -+- (negative + negative) so the response is, is that if two integers where both negative, you would add, just like if there were two positives, you would add, but not if you have different signs. (positive+negative) you would subtract. Just as the same with negative + positive. [REVIEW: if the sign is the same, add, if the sign is different, you subtract.] *=you may not always add *=integers- a fancy word for numbers.

Why is it important to learn how to subtract and add with different integers?

Because otherwise you would only know how to subtract and add with the same integers. Not a particularly useful skill unless just those integers turned up!
