Question

Draw a number line and answer the following:

(a) Which number will we reach if we move 4 numbers to the right of − 2.

(b) Which number will we reach if we move 5 numbers to the left of 1.

(c) If we are at − 8 on the number line, in which direction should we move to reach − 13?

(d) If we are at − 6 on the number line, in which direction should we move to reach − 1?

Answer 1

(a)

We will reach at 2, if we move 4 numbers to the right of −2.

(b)

We will reach at −4, if we move 5 numbers to the left of 1.

(c)

Clearly, −13 is to the left of −8. Therefore, we should move towards the left direction.

(d)

Clearly, −1 is to the right of −6. Therefore, we should move towards the right direction.
