I'm trying to accomplish the following. I want to symbolically show calculations along the way to enable basic troubleshooting. Easy enough, but in the later equations I only want the prior results to be shown, while mathcad prime continues to plop in the whole equation even if it's been evaluated. Here's my very simple sample. I'd like to simplify the expression for Ptot by showing the previous results. But I can't seem to get there easily. File attached. Thanks!
