Examples
A convenient shorthand that I use frequently is the "double slash" notation to string commands together. For example, I can write:
x - 1 + x^2 //TraditionalForm
And receive back:
x^2 + x - 1
Or another example:
(x - 1)(x + 2) //Expand //TraditionalForm
Yields:
x^2 + x - 2
However, I have never been able to find a way to input multiple arguments into a function using this notation. That is, I cannot call something like:
x^2 + 9x + 5, 3 //PolynomialMod
Obviously the above can easily be written as:
PolynomialMod[x^2 + 9x + 5, 3]
(but what's the fun in that?)
Question
Is there a way to input multiple parameters using the shorthand postfix operator?
