Hello everyone, I would like to be able to display equations for my students in symbolic form on the left side and with the numbers plugged in on the right side but am not quite sure how to do it programmatically. Suppose my equation in "symbolic" form is sqrt(x^(a+b)) + c ln(d/e) I know I can make it look like real math by having it displayed as TraditionalForm. However, I also want to display the solution with particular values for the variable x and the parameters a, b, c, d, and e slotted in, something like sqrt(x^(a+b)) + c ln(d/e) = sqrt(9^(2+1)) + 4 ln(32/8) = answer to recognize that some students may be a little rusty at simplifying on the fly. Wrapping the whole package in Manipulate would put the icing on the cake. Any tips on how apply the appropriate styles would be most appreciated. Regards, Gregory
