First PTC Mathcad Content!
You may be aware that I write a blog for PTC on Mathcad, their engineering calculation software (and I used to teach Mathcad). One area I've found that sometimes confuses students is the different equals signs and their uses. This document shows the different signs, their keyboard shortcut, and how they are used.
PTC Mathcad Express can be downloaded for free, so I highly recommend you start using it today!
