Natural numbers begin from 0 or 1?... now according to modern maths do we consider set of positive integers as natural numbers {0,1,2...}?

""Some definitions, including the standard ISO 80000-2,^{[1]} begin the natural numbers with 0, corresponding to the **non-negative ****integers**0, 1, 2, 3, …, whereas others start with 1, corresponding to the **positive integers** 1, 2, 3, ….^{[2]}^{[3]}^{[4]}^{[5]} Texts that exclude zero from the natural numbers sometimes refer to the natural numbers together with zero as the **whole numbers**, but in other writings, that term is used instead for the integers (including negative integers).""(SOURCE:WIKIPEDIA)
