NCERT Class 6 Mathematics (Maths-World) book chapter "The Other Side of Zero" introduces the concept of Negative Numbers and Integers. On page number 265, the "Figure it Out" section helps students practice placing and identifying numbers on a vertical or horizontal number line.

Solutions: Figure it Out (Page 265)

Question 1: Mark the following numbers on the number line.

The question asks you to plot specific integers like $-3, +5, -2, 0, and +1 on a standard number line.

Solution:

1. Draw a straight horizontal line.

2. Mark a point in the centre as 0.

3. Points to the right of 0 are positive (+1, +2, +3, +4, +5).

4. Points to the left of 0 are negative (-1, -2, -3, -4,-5).

5. Simply place a dot or an 'X' on the specific values mentioned in your exercise.

Question 2: Vertical Number Line (Temperature or Elevation)

Often on this page, there is a task involving a vertical number line (like a thermometer) to show that:

• Above zero is positive (+).

• Below zero is negative (–).

Solution Strategy:

• If the question asks for "5 degrees below zero," students move 5 steps down from 0 to reach -5.

• If it asks for "10 meters above sea level," you move 10 steps up from 0 to reach +10.

Question 3: Comparison of Integers

Students may be asked to determine which number is greater.

• Rule: Any number to the right on a horizontal line (or higher on a vertical line) is always greater.

• Example: Between -2 and -5, -2 is greater because it is closer to zero and further to the right.
