What does it mean to add integers?

Back

Adding integers involves combining their values. If both integers are positive, the result is positive. If both are negative, the result is negative. If one is positive and the other is negative, subtract the smaller absolute value from the larger absolute value and take the sign of the integer with the larger absolute value.
