subtracting integers (rule)

• subtract their absolute value; keep the sign of the integer with the higher absolute value

• add their absolute value and keep the sign of the integers

• change subtraction sign (between the integers) to an addition sign and change the sign of the integer following it to its opposite (if it was positive, make it negative; if it was negative, make it positive); then solve
