What are the rules of adding and subtracting integers?
Rules for Adding Integers
| Rule | Examples | |
|---|---|---|
| Addition of two positive numbers | (+a)+(+b) = (a+b) | 3+4=7 2+11=13 |
| Addition of a positive number and a negative number | (a+(-b)) = (a-b) | 4+(-5)=(-1) (-5)+7=2 |
| Addition of two negative numbers | (-a)+(-b) = -(a+b) | (-2)+(-4)=(-6) (-5)+(-8)=(-13) |
What are the rules for combining integers?
Adding Integers Rules
- The sum of an integer and its additive inverse or opposite is 0.
- Adding two positive integers always results in a positive value that is greater than both the integers.
- Adding two negative integers always results in a negative number that is smaller than the given numbers.
What are the 2 Rules In subtracting integers?
To subtract two integers, rewrite the subtraction expression as the first number plus the opposite of the second number. Some examples are shown below. To subtract two integers, add the opposite of the second integer to the first integer. This can be written symbolically as a – b = a + (-b).

What is the rule for integers with the same sign?
Now apply the rule. Add the integers with the same sign. The answer is kept with the same sign. When the positive sign, and the negative sign of the integer 2 get multiplied with each other it gives a negative sign. Then add the integers with the same sign and keep the answer with the same sign.
