If you add a negative number to something you go left on the number line (minus direction).
5 + (-4) = 5 - 4 = 1
Therefore if you subtract a negative number from something, you go right on the number line (plus direction).
5 - (-4) = 9
5 + (-4) = 5 - 4 = 1
Therefore if you subtract a negative number from something, you go right on the number line (plus direction).
5 - (-4) = 9
