It makes for a more elegant (imho) recursive definition of the sum. Instead of: a + S(b) = S(a) + b a + 0 = a you would have: a + S(b) = S(a) + b

It makes for a more elegant (imho) recursive definition of the sum. Instead of:
a + S(b) = S(a) + b
a + 0 = a
you would have:
a + S(b) = S(a) + b
a + 1 = S(a)
And also you would not be able to express 1 as a sum of two numbers.
