How do you add integers if they are the same sign?
Add the magnitudes of the integers (-4 has a magnitude of 4), then take the sign to the answer.
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.
What are the rules of addition?
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.
How do you add integers with the same sign?
Add the magnitudes together, and take the sign. Example: 4 + 5 {both are positive} so it's +9 {or just 9}. Now: -3 + -2 {both are negative}. Add the magnitudes (3 + 2 = 5) and take the sign, so it's -5.
What is a rule that states how to determine the sum of any two integers that have the same sign?
Add the number together and give the answer the same sign as the numbers.
