Add their magnitudes, and keep the same sign for the sum.
To add two integers with opposite signs . . . -- Ignore the signs, and write the difference between the two numbers. -- Give it the same sign as the larger original number has.
Step 1. Ignore the signs, and subtract the smaller unsigned number from the larger one. If the answer is 0, you're done. Otherwise, do step 2. Step 2. Apply to the answer the sign of the given number with the larger magnitude. For example, 5 + (-2) is 3; 12 + (-23) is -11.
The sum of any two numbers has the same sign as the number with the greater absolute value.
The same way you'd add any other negative numbers. Adding a negative is the same as subtracting, and subtracting a negative is the same as adding. (-2) + (-2) = (-4) (-2) - (-2) = 0 you are wrong if you add or subtract two negitives its always a positive dont you know your math. And the second problem you have is wrong to because when you subtract two negitives you change the sign of the secong number to positive and you change the subtraction sign to a addition sign.

Add the number together and give the answer the same sign as the numbers.
If you mean integers, well if you have two integers of the same sign that you are adding, add and the sign stays the same. If you have different signs, subtract and keep the sign of the one that has more. Regular numbers you just add them.

copy the sign then add :)
Step 1. Ignore the signs, and subtract the smaller unsigned number from the larger one. If the answer is 0, you're done. Otherwise, do step 2. Step 2. Apply to the answer the sign of the given number with the larger magnitude. For example, 5 + (-2) is 3; 12 + (-23) is -11.
-- Temporarily ignore the signs. -- Add the numbers without their signs. -- Give the sum the same sign as the original two numbers have.
-- 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.

The absolute value of the answer is the difference between the absolute values of the two numbers and the sign associated with it is the same as that of the number with the greater absolute value.
You simply add the numbers. If the sign is positive with both numbers, the sum will be positive. 1 + 3 = 4 If the sign is negative with both numbers, the sum will be negative. -1 + -3 = -4
