1. Identify the integers you need to add. Integers are whole numbers, both positive and negative, and can include zero.
2. If the integers have the same sign, add their absolute values (the values without their signs) and then keep the same sign. For example, to add -3 and -5, you would add 3 and 5 to get 8, and then keep the negative sign, so the answer is -8.
-3 + (-5) = -8
3. If the integers have different signs, subtract their absolute values and then keep the sign of the larger absolute value. For example, to add -3 and 5, you would subtract 3 from 5 to get 2, and then keep the sign of the larger absolute value (5), which is positive, so the answer is 2.
-3 + 5 = 2
