Can you help me write down the induction proof for this statement? thank you.

Induction.
For m, n E Z+, define P(m, n) to be:
(п + т — 1)!
n!(m – 1)! `
the number of ways to write n = x1 + · . .+ xm with x1,... , xm E N is
(a)
Prove each of the following statements.
i. Vm,n € Zt,P(т, п + 1) л Р(т + 1,п) 3> P(m + 1,n + 1).
