MathAction #150 To create a function from an expresion

Topics

I don't now how ... If I enter:

fricas

(1) -> expr:= 3*x

$\label{eq1}3 \ x$

Type: Polynomial(Integer)

fricas

f(x) == expr

Type: Void

fricas

f(5)

fricas

Compiling function f with type PositiveInteger -> Polynomial(Integer
      )

$\label{eq2}3 \ x$

Type: Polynomial(Integer)

I get an output of ; I would like an output of 15. Is there a way to do it right?
