Thanks to two private messages for suggesting the Simplify function. Simplify does work for the simple problem I posed, but not for the more complicated problem I was thinking about. The problem I proposed is solved by Simplify: ((A/B) - C)/D // Simplify (A - B C)/(B D) But my real problem doesn't solve as easily, (-1 - (2 Gamma[n/2]^2)/Gamma[1/2 (-1 + n)]^2)/n even if assumptions are imposed: FullSimplify[%, {n >= 2, n \[Element] Integers}] Many thanks for any suggestions.
