Question

Person A is at number 9 on a number line. He moves 2 steps to left and then another 5 steps to the left, where is he standing now?

Answer 1

When we move to the left on a number line, we are actually subtracting.

From 9, 2 steps to the left is 9 -2 = 7

Another 5 steps to the left is 7 - 5 =2.

Hence person A will now be on number 2 on the number line.
