Which operation is shown on the number line?

• 8 + 6 = 14

• 8 + 2 = 10

• 8 - 6 = 2

• 8 - 2 = 6

Answer explanation

Arrowhead points towards the left of 8. This suggests that some number is to be subtracted from 8. Arrows move two steps towards left from 8, therefore 2 should be subtracted from 8. We get, 8 - 2 = 6
