The value of (u)(q)(v)(p) is 23*(1/23) = 1.
Note that the multiplicands in (u)(q)(v)(p) can be arranged in any order without affecting the final outcome (product). (u)(q)(v)(p), in this sense, is exactly the same as pq*uv, or just pquv, or (pq)*(uv).
The rule that applies here is the commutative rule for multiplication.
