For two positive integers $m$ and $n$, define an operation "⊙" as follows: when $m$ and $n$ are both even or both odd, $m⊙n=m+n$; when one of $m$ and $n$ is even and the other is odd, $m⊙n=mn$. Under this definition, the number of elements in the set $M=\{(p,q)|p⊙q=10, p\in\mathbb{N}^*, q\in\mathbb{N}^*\}$ is.
