What is the easy way to do adding and subtracting integers

Adding and subtracting integers is easy ... u just need to know some rules of integers

(ie) (+) and (+) = +

(-) and (-) = +

(+) and (-) = (-)

If it is one negative and the other is positive, subtract like normal but take the sign of the larger distance from zero. If positive, do as normal. If negative, subtract as if there were no signs and then make it negative.
