Mastering Integer Operations

To add integers, you simply combine the values of the integers. If the integers have the same sign, add their absolute values and keep the common sign. If the integers have different signs, subtract the smaller absolute value from the larger absolute value and keep the sign of the integer with the larger absolute value.

To subtract integers, you change the sign of the integer to be subtracted and then follow the rules for adding integers. In other words, you add the opposite of the integer you want to subtract.

Sure! Let's say we want to add 5 and 3. We add their absolute values (5 + 3 = 8) and keep the common positive sign, so the result is 8.
