History Display

Our calculator keeps a record of all the calculations that have been performed. This information is presented to the right of the calculator on desktop/tablet view and below the calculator on mobile view. The history is displayed in a modal window and shows the calculation, as well as the operands and the result. This feature makes it easy to go back and review previous calculations if needed.

Select & Use Results History

This feature allows the user to select and reuse a previous calculation from the calculator's history. When the user clicks on a previous calculation in the history, the result of that calculation is displayed in the main calculator display, allowing the user to reuse the result in a new calculation. This feature can be especially useful when the user needs to perform multiple calculations with the same result or needs to reference a previous calculation without having to redo the entire calculation.

Reset All Button

Our calculator also has a "Reset All" button that clears both the calculator display and the history. This button can be used to start fresh and clear any previous calculations that have been performed. This feature is especially useful if you have been using the calculator for a while and want to start over with a clean slate.
