I am wondering if it is possible to get a result like this:

f(x):=2*x+5

x:=10

f(x)=2*10+5=25

I mean that Mathcad puts the x and shows the first step because retriving only f(x)=25 is less usefull than seeing from what values it is done

I do not want the programm to do it step by step like

f(x)=2*10+5=20+5=25

I just need to see the first step

ofc it is just a simply example to make it clear

Mathcad's explicit,ALL is right - the results are derived by picking a specific element from a vector and this is shown.

I know what you want to see, but it looks you can't get it.

The closest I could come up with was using the full vectors and the vectorization operator. See attached.

There is only very limited support for what you are asking for using symbolic evaluation with keyword "explicit", but it doesn't do what you demand if used for the function definition.

Thats exactly what explicit will do, unfortunately it shows the first step only, not the following. In case of f(x) the first step is to insert 10 for x.

I forgot to mention that I work in Prime 2.0

So according to what you say there is no chance that if I have a lot of defined functions and a set of variables and now I could change it in one line

Thank anyway it is still much easier!

"explicit" should work in Prime the same way
