Common Core State Standards Learning Objective 7.NS.1a & b Add and Subtract Rational Numbers on a Number Line
Using a number line to add integers –6 –5 –4 –3 –2 –1 0 1 2 3 4 5 2 Adding Integers with Different Signs (–6) + 2 To add a positive number move to the right. To add a negative number move to the left. Start at the first number (-6) From –6, move right 2 units. You finish at –4, so (–6) + 2 = –4.
–6 –5 –4 –3 –2 –1 0 1 2 3 4 5 –6 –5 –4 –3 –2 –1 0 1 2 3 4 5 7 7 –3 + 7 Examples Start at the first number (-3) From –3, move right 7 units. You finish at 4, so (–3) + 7 = 4. –7 + 7 Start at the first number (-7) From –, move right 7 units. You finish at 0, so (–7) + 7 = 0.
