**What are the rules for subtracting integers with different signs?**

Subtracting two integers with different signs is done by changing the sign of the integer that is subtracted. Then, we need to check if both the integers become positive, the result will be positive and if both the integers are negative, then the result will be negative.

### What is the rule in subtracting integers with different signs?

### What is the rule of adding and subtracting integers?

To add integers having the same sign, keep the same sign and add the absolute value of each number.

Subtract an integer by adding its opposite.

**How do you subtract positive and negative numbers?**

#### How do you subtract two 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).
