Represent the following numbers on a number line: (a) + 5 (b) ? 10 (c) + 8 (d) ? 1 (e) ? 6 TIPS Firstly, draw a number line, then represent a negative integer on the left of zero on the number line and a positive integer on the right of zero on the number line.

Answer:

Draw a line and mark some points at equal distance on it. Mark a point as zero on it. Points to the right of zero are positive integers and are marked by +1, +2, +3 or simply by 1, 2, 3, etc. Points to the left of zero are negative integers and are marked by ?1, ?2, ?3, etc. (a) Representation of + 5 To mark + 5 on number line, we move 5 points to the right of zero as shown in the figure. In the above figure, point A represents +5. (b) Representation of ? 10 To mark ? 10 on number line, we move 10 points to the left of zero as shown in the figure. In the above figure, point A represents ? 10. (c) Representation of +8 To mark +8 on number line, we move 8 points to the right of zero as shown in the figure. In the above figure, point A represents +8. (d) Representation of ?1 To mark ?1 on number line, we move 1 point to the left of zero as shown in the figure. In the above figure, point A represents ?1. (e) Representation of ?6 To mark ?6 on number line, we move 6 points to the left of zero as shown in the figure. In the above figure, point A represents ?6.
