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:

(a) On number line, starting from ?2 and moving 4 points towards right (each step being equal to 1 unit), we will reach at 2. (b) On number line, starting from 1 and moving 5 points towards left (each step being equal to 1 unit), we will reach at ?4. (c) Here, ?8 > ?13. So, ?13 is on the left of ?8. Hence, if we are at ?8 on number line, then move to the left from ?8 to reach at ?13. (d) Here, ?1 > ?6. So, ?1 is on the right of ?6. Hence, if we are at ?6 on the number line, then move to the right from ?6 to reach at ?1.
