Is there a way to extensively use postfix notation for input in Mathematica? I know you can enter F[x] as x//F, but I can't seem to make it work for multiple arguments. For example N[Sqrt[7]] can be input as 7//Sqrt//N, but I can't figure out how to input N[Sqrt[7],30] or even Plus[3,5]. Is this type of input not really supported? Is there a way to work around it? Thanks for your help.
