Question :
What is the difference between Measurement Numbers and Ordinary Numbers ?

Answer :
Measurement numbers are very much like the ordinary numbers in arithmetic. They can be added, subtracted, multiplied and divided. However while doing these operations one has to convert all measurement numbers into the same units.
For Example,
We cannot add 4 feet and 9 inches, we have to convert so that both measurements are either in foot units or inch units.
