Integers Rules ADDITION When we ADD a POSITIVE number we move UP the number line. e.g. (-3) + 7 = 4 When we ADD a NEGATIVE number we move DOWN the number line. e.g. 2 + (-8) = -6 SUBTRACTION When we SUBTRACT a POSITIVE number we move DOWN the number line.ntegers Rules ADDITION When we ADD a POSITIVE number we move UP the number line. e.g. (-3) + 7 = 4 When we ADD a NEGATIVE number we move DOWN the number line. e.g. 2 + (-8) = -6 SUBTRACTION When we SUBTRACT a POSITIVE number we move DOWN the number line.
