1. The problem is to represent given numbers on a number line. 2. A number line is a straight line where each point corresponds to a real number. 3. To represent numbers, we mark points on the line corresponding to their values. 4. For example, if the numbers are $-3$, $0$, and $4$, we place points at these positions on the line. 5. Negative numbers are to the left of zero, positive numbers to the right. 6. Zero is the origin point on the number line. 7. This visual helps understand the order and distance between numbers.
