Addition rule for integers
To add integers, if the signs are the same, add the numbers and keep the sign. If the signs are different, subtract the smaller number from the larger one and keep the sign of the number with the greater absolute value.

What is the rule for subtracting integers?
Keep the first number the same, change the subtraction sign to addition, and change the sign of the second number to its opposite. After these changes, follow the rules for adding integers. If both numbers have the same sign, add their absolute values and keep the common sign; if they have different signs, find the difference of their absolute values and use the sign of the number with the larger absolute value.
