Our Basic Calculator is the same 15-feature easy-to-use basic calculator that's on our home page.  The difference is this has no ads, no frame, and makes no network calls, even for images.  So it's fast, does not spy on you, and does just what you request.  Can be used locally on a secure device.

It remembers its calculations when closed, so when opened again, the calculator is just where the user left off, even if that was in the middle of a calculation.  Nice :-)

Calculator is delivered as a single HTML file (~50KB), and can be used on any device that has a browser, such as touchscreen devices, desktop PCs, laptops, iPads, smartphones, etc.

This proven calculator is perfect for use in meetings, classes, presentations, at home, and is designed for frequent all-day use.
