All positive numbers, negative numbers, and zero can be put on number line.
The following is a number line showing integers from -7 to 7. However, the arrows at both ends show that the numbers do not stop after 7 or -7 but the pattern continues.
You may have noticed that all numbers on the right of zero are positive. On the other hand, all numbers on the left of 0 zero are negative.Opposites numbers are located at the same distance from zero.
The distance a number is from zero is called its absolute value.
Notice that the absolute value of a number is always positive.
