Here are the rules:
INTEGER ADDITION
You can tell it's integer addition if there is a + sign in between the numbers.
When the signs are the same, ADD, and keep the same sign.
Examples: 6 + 7 = 13 (-6) + (-7) = -13
(Some books and worksheets will use the parentheses to make it clear that the negative sign goes with the number and isn't a subtraction sign.)
When the signs are different, SUBTRACT, and use the sign of the bigger number. (whichever number is bigger ignoring the sign)
(-5) + 3 = -2 The signs are different, so you subtract 5 - 3 to get 2. Then, since 5 is bigger than 3, you use the negative sign.
7 + (-10) = -3 The signs are different, so you subtract 10 - 7 to get 3. Since 10 is bigger than 7, you use the negative sign.
(-2) + 9 = 7 The signs are different, so you subtract 9 - 2 to get 7. Since 9 is bigger than 2, the answer is positive.
INTEGER SUBTRACTION
You know it's subtraction when there is a minus sign between the numbers.
It's much easier to change all subtraction problems into addition problems by following these steps:
1. Change the minus sign to a plus sign and changing the sign of the next number.
2. Follow the rules for integer addition.
(-5) - 3
Change the minus to a plus and change the 3 to a -3. Like this:
(-5) + (-3)
Now, since the signs are the same, add and keep the same sign. The answer is -8. Basically, we are giving the 3 the negative sign.
Here's another example:
10 - (-2)
You see "minus a negative" here so change it to "plus a positive" (click, click!)
10 + (+2)
Now, since they are both positive, just add! The answer is 12.
Here's one more:
2 - 14
Change the minus to a plus and change the 14 to -14.
2 + (-14)
The signs are different, so subtract 14 -2 and get 12. Then, 14 is bigger than 2, so the 12 is negative. The answer is -12.
