To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

What are the rules for adding and subtracting integers?

While adding two integers with different signs, subtract the absolute values, and write down the difference with the sign of the number which has the largest absolute value. (+6) + (-4) = +2.
