Enter simple or complex mathematical expressions and immediately calculate the result. From adding your grocery bill to calculating cosine, CalculateX does it all. Results are added to a history tape, so you don't have to write them down to remember them. Those results are even saved and restored when you exit and restart the application. A significant percentage of Enterprise deployments of Windows result in a broken Windows Calculator app. In addition, many companies do not allow users to install applications from the Microsoft Store. If this is the situation at your company, you can purchase CalculateX at and I will email CalculateX to you. The original application was an open-source project from Calculator.NET from Loresoft. I forked the project, fixed some bugs, added new features, rewrote it in .NET 5 and WPF, and published it to the Microsoft Store.
