Get shown the formula behind a defined value

[AJ_10300133]

Hello 

Is there a way to get shown a the formula behind a value. 

For example:

If i define value for "e" = ((250/2)-(250/3)) = 41,67

is there a way to show the formula when later in the dokument i want to use the value "e", but i want to show how it was determined? 

when i try to show it now it only shows e = 41,67?

best regards AJ

Yes, using symbolic evaluation (not =, but right-arrow), example:

But it doesn't work with your numbers example, because the symbolics get simplified:

If you want to show how an answer is determined, use the same (symbolic) evaluation, and use the keyword 'explicit'.

Look that up in the help.

Success!

You could use the symbolic evaluation with "explicit,ALL"

Future versions of Prime may be able to hide the keywords and show the arrow as an equal sign as good old Mathcad could do (here Mathcad 15):
