Skip counting is a way that we can perform addition or subtraction of whole numbers.

Consider the numbers fifty (50) and one hundred (100).

On the real number line, skipping from 50 to 100 can be thought of as adding 50 to 50 in order to obtain 100.

Similarly, moving from 100 to 50, can be thought of as subtracting 50 from 100 to obtain 50.

The distance between 2 numbers on the number line is termed as the interval between the two numbers. In our example above, we can therefore say that we are skipping in an interval of 50 to the right, or to the left.

This implies:

\(*\) Movement to the right on the real number line means addition.

\(*\) Movement to the left on the real number line means subtraction.
