The standard calculator widget is a simple and user-friendly tool that can help you perform basic arithmetic calculations. The calculator will resemble many basic device calculators, with buttons for numbers, basic operations, and functions. Start by entering the first number of your calculation using the number buttons. After entering the first number, select the operation you want to perform using the buttons on the calculator, such as addition, subtraction, multiplication, or division. Then, enter the second number of your calculation using the number buttons. To calculate the result, click the "=" button on the calculator. The calculator will display the result in the calculator window. If you want to perform a new calculation, use the "C" button to clear the calculator window.
