thank you for the answer,
its close, but still not what i want, i would like to get all of the substitutions and final result (with arbitrary accuracy and units) in the same line and in a clear format( i need only some narrative text, equations->subtitution the variables and the final result (important to see the value of the variables) like in a book), without `` and other stuff, of course i can hide a lot of line, but its still a lot of work to get the right units and formats
i want to make a static calculation of structures, im using  mathcad too, but there i have some problem with the substitution
so if anybody know a great software for document the static calculation (mainly bridges) pls let me know (a maple solution would be the best), thanks
