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 to 1?

(c) If we are at - 8 on the number line, in which direction should we move for each - 13?

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

Answer:

(a) We start from - 2 and proceed 4 units to the right of - 2 to reach 2 as shown in the figure.

Hence, we will reach the number 2.

(b) We start from 1 and proceed 5 units to left of 1 to reach - 4 as shown in the figure.

Hence, we will reach the number - 4.

(c) If we are at - 8 on the number line and we want to reach - 13 then we should move to the left of - 8,

\[\therefore \]\[13<8\].

(d) If we are at - 6 on the number line and we want to reach - 1 then we should move to the right of - 6.

\[\therefore \] \[1>6\]
