Sir u told whole number came first but in number system natural numbers are first.
Sir in maths always a numbers starts from 0 but in natural numbers numbers starts from 1
Zero as a numeral was not "invented" until 1000 years ago in India. Up until that time, a place holder was used or the "space" was left blank. The concept of "nothing or null". Existed before the numeral was created. So, n effect in a natural number system 1 is the first numeral because zero as a numeral did not exist. Thus: null or nothing, 1,2,3,4.....
In math, zero is the symbol that represents null. Thus: 0,1,2,3,4....
Basically the same.
