The magnitude of the sum is the difference between the magnitudes of the two numbers.
The sign of the sum is the sign of the number with the larger magnitude.
(The "magnitude" of a number is just the size of the number without any sign.)

Adding IntegersTo add integers, one must consider the following two rules to be a successful.If you want to think of it on the number line you start from 0 and when you add a positive number you go that much to the right, and when you add a negative number you go that much to the left. When adding two positive integers, just add like normal. When adding one positive integer, and one negative integer, it is like subtracting a positive number from a positive number. When adding two negative integers, it is like subtracting a positive number from a negative number.
With both positive it's positive, with both negative it's negative.
when you add two positive integers the answer is always positive when you add two negative integers the answer is positive when you add one negative and on positive integer, the answer is negative subtracting two negative numbers gets a negative answer subtracting two positive numbers- the answer depends subtracting a negative and positive number- the answer depends, the positive number would have to be bigger than the negative to achieve a negative number, and if the positive number is less, than the answer is still negative
When you add: a negative and a negative: you get a negative a positive and a positive: you get a positive a positive and a negative or a negative and a positive: Subtract the addend with the smaller value from the greater one. If the greater one is positive, your answer will be positive. If the greater addend is negative, your answer will be negative.
Rule: Positive + Positive = Positive 12+12=24 Positive - Positive = Positive or Negative 12-6=6 | 12-13=(-1) Positive + Negative = Greater numbers sign in the answer 14+(-18)=(-4) | 18+(-14)=4 Positive - Negative = Positive 8-(-8)=16 Negative + Negative = Negative -12+(-12)=(-24) Negative - Negative = Positive or Negative (-8)-(-9)=1 | (-8)-(-7)=(-1) by, Patrick Macarilay AKA, macason
