Explicit Variable Values

Hello

is there a function for making Mathcad rewrite an expression with the variable Values, ie:

a= 500 b =200

a*b-----> 500x200=10000

Its just for copying and pasting in word.

.Thanks in advance

Cheers

You can do the following:

The explicit keyword is in the symbolic menu.

ok, i didnt now i had to indicate wich one i want to "explicit", is there a way for explicit all of them without indicating? i have various equations with 10 variables.

Yes. Try: a*b explicit, ALL.

Incidentally, if you want to hide the explicit keywords you can do the following:

Better to do so:

a:=2cm b:=3cm

...

...

...

c:=a*b=5cm^2

where

a=2cm

b=3cm

Better for units and Prime

Really? Is this the result when using Prime?

.. but maybe not better for what Ibarra has in mind.

And Ibarra has shown in previous posts that he is using Mathcad 15, not Prime.

Its necessary to do as you suggest because Prime does not offer the ability to hide the keywords and does not offer different representations for the symbolic evaluation arrow or the assignment :=

Mathcads explicit is by no means perfect and will not always give you what you want the way you want, but when it comes to simulate the usual syntax used by many in documentations, its nice benefit that a least good old real Mathcad can produce something like

and its a shame that Prime can't.

BTW, I normally don't like when people show an assignment as normal equal sign as I am used to Mathcad's systax and appreciate to be able to see at a glance if an expression is an assignment or an evaluation. But in a report for non-tech or lets say for People not used to Mathcad, this might make sense.

We need explicit for manual check of calculation: 2*3=5?
