Understanding the Default Interface

The default view of the Windows 11 Calculator app is the "Standard" mode. It mimics a traditional handheld calculator, with buttons for numbers (0-9), basic arithmetic operations (+, -, \ , /), a decimal point (.), and equals (=).

Number Pad: The large number pad in the center of the app is where you input the numbers you want to calculate. You can click on the numbers with your mouse or use the number keys on your keyboard. Both work equally well.

Operation Buttons: To the right of the number pad, you'll find the operation buttons: addition (+), subtraction (-), multiplication (\ ), and division (/). These buttons perform the corresponding arithmetic operations on the numbers you input.

Equals Button: The equals (=) button is used to calculate the result of your expression. After entering your numbers and operations, click the equals button to display the answer.

Clear Buttons: There are two clear buttons: "C" and "CE." The "C" button clears the entire calculation, resetting the calculator to its initial state. The "CE" button (Clear Entry) clears only the last number you entered, allowing you to correct mistakes without starting over from scratch.

Memory Functions: The "MS," "MR," "MC," and "M+" buttons are memory functions. These allow you to store numbers in the calculator's memory for later use. "MS" stores the current number in memory, "MR" recalls the number from memory, "MC" clears the memory, and "M+" adds the current number to the number stored in memory. This can be handy for complex calculations involving multiple steps.

Percent Button: The "%" button calculates the percentage of a number. For example, to calculate 20% of 100, you would enter "100 20 %".
