For more than 20 years, Mathcad has been the standard for technical computing and engineering calculation documentation. Mathcad is a better way to manage your engineering calculations than spreadsheets (which hide equations behind cryptic expressions) or computation programming languages (which have steep learning curves). Mathcad uses real math notation that looks and behaves just like the formulas in your engineering reference books. Mathcad calculations are easy to create, understand, audit, share, and troubleshoot.
