What are Nominal Numbers ?

Numbers used to name something eg. Blk 543, a bus number 963 or your IC No. 7612345B.

How we have often mistaken the bus numbers to be nine hundred and sixty three, instead of "9" "6" "3".

What are Ordinal Numbers ?

Ordinal numbers are used very often to label the position of children lined up in a row, eg. 1st, 2nd, 3rd, 4th, 5th etc.
