This paper presents a simple bijection proof between a number and its combina-torial representation using mathematical induction and the Hockey-Stick identity of the Pascal's triangle. After stating the combinadic theorem and helping lemmas, section-2 proves the existence of combinatorial representation for a non-negative natural number.

Application This identity is used in problem 660E - Different Subsets For All Tuples. Leave a comment if you know other problems for it. In practice Naturally, if we want to calculate the binomial, we can for example use the formula $$$ \displaystyle \binom {n} {k} = \frac {n!} {k! (n-k)!} $$$ and do the division using modulo-inverse.

The hockey stick identity is an identity regarding sums of binomial coefficients. For whole numbers n n and r\ (n \ge r), r (n ≥ r), \sum_ {k=r}^ {n}\binom {k} {r} = \binom {n+1} {r+1}. \ _\square k=r∑n (rk) = (r+ 1n+1). The hockey stick identity gets its name by how it is represented in Pascal's triangle.
