First Class Session
In class today, we learned about the uses of numbers and I have learned 2 new terms - rational numbers and nominal numbers. We had been using the latter in our daily lives such as our I/C numbers, phone numbers, bus numbers and etc. It's just that most of us didn't know the name of it.
nominal numbers: numerals with no information other than identification purpose (name)
rational numbers: any numbers that can be expressed as a fraction
