RE: Intermediate computational results
The Presentations package has routines EvaluateAt and EvaluateAtPattern for evaluating held expressions in a controlled manner. It also has facilities for creating formatted displays in any format, including graphics and dynamic elements, and hiding all the Input specifications. An example using a two column display with comments on one side and output on the other side (with tooltips that show the Input statements) will be posted on Peter Lindsay's site: Peter Lindsay at the Mathematical Institute in the University of St Andrews [ www.mcs.st-and.ac.uk ] has kindly undertaken to maintain an archive that provides downloadable notebooks and PDF files for various Presentations solutions that have appeared on MathGroup. http://blackbook.mcs.st-and.ac.uk/~Peter/djmpark/html/ David Park djmpark at comcast.net http://home.comcast.net/~djmpark/ From: TL [mailto:latev at shaw.ca] I have a mathematical expression and I have to demonstrate a real world example - an actual computation using the formula. For that purpose I'd like to show all intermediate steps, not just the final result. Is there a way to tell Mathematica to do one step at a time and not just show the final result? For example A=B+CD B=10 C=11 D=12 A=10+11x12=10+132=142 In other words I wouldn't like to type in all the equations with the exact numerical values.
