Question

Mark the integer $-3$ on the number line.

Answer 1

Step 1: Draw a line and mark some points at equal distances as shown in the figure. Mark a point as '$0$‘ on it. Points right to the ’$0$' are positive integers and are marked as$1,2,3$ and so on and points left to the ‘$0$’ are negative integers and are marked as$-1,-2,-3$ and so on.

Step 2: In order to mark ‘$-3$’ on it, move $3$ points to the left of $0$.

Therefore, the integer shown in figure is $-3$.
