Windows Calculator Overview

Windows Calculator offers three basic modes: standard, scientific, and programmer. Standard mode is what you would expect from a typical basic calculator, with addition, subtraction, multiplication, and division. Scientific mode adds exponents and trigonometric functions, and programmer mode allows you to perform operations related to computer programming.

Windows Calculator Features

In addition to the three main modes, Windows Calculator has several other useful features.

Date Calculation: Access the menu located in the upper left corner to find the date calculation feature. This tool proves valuable in determining the gap between two dates, which is particularly beneficial for creating schedules or timelines.

Converter Functions: Further down this menu, Windows Calculator offers several converter functions, including currency, volume, length, weight and mass, temperature, energy, area, speed, time, power, data, pressure, and angle.

Easy to Use and Read: Windows Calculator is easy to use, and you can input numbers with the keypad, mouse, or by using the touch screen. The numbers are large and easy to read. The calculator can be enlarged to full screen size, or kept small.

History and Memory Tracking: The calculator keeps track of your history and memory in a panel on the right side. To show this panel, simply put your mouse arrow over the right edge until a double arrow appears, and slide it to the right. To hide the panel, hover over the right edge and slide it to the left.

The calculator app stays on top of your other tabs. If you are using the calculator along with other tabs, you will need to click in another place on the screen, or minimize the calculator. This can be a bit cumbersome if you have a lot of tabs open or are trying to work quickly.
