Calculator Modes: Windows Calculator offers several modes to cater to various needs.

Standard Mode: This is the default mode and lets you perform basic arithmetic operations.
Scientific Mode: To access additional functions like trigonometry, logarithms, and factorial, click on the "View" menu in the Calculator app and select "Scientific".
Programmer Mode: If you work with binary, octal, decimal, or hexadecimal numbers, you can enable Programmer mode via the "View" menu.
Date Calculation Mode: This mode helps you calculate the difference between two dates. Ensure you're in Standard mode, click on "View", and select "Date Calculation".

Using the Calculator:

Number Keys: Type numbers using both your keyboard and the number pad on your computer.
Arithmetic Operations: Use the common arithmetic buttons (+, -, *, /) for addition, subtraction, multiplication, and division respectively.
Memory Functions: The calculator includes memory features. You can use "MC" to clear the memory, "MR" to recall it, "MS" to save a value into memory, and "M+" to add to the memory value.
Clearing the Calculation: To clear the calculation, use "CE" to delete the current number or "C" to clear everything.
Backspace: In case you make a mistake, use the "Backspace" key to remove the last entry.

Switching Calculator Modes: To switch between different modes, click on the "View" menu and select the desired mode.

Using Scientific Mode

If you need to perform advanced mathematical calculations, you can switch to the Scientific mode within Windows Calculator. Here's how:

Switch to Scientific Mode: Click on the "View" menu and select "Scientific".
Additional Functions: Scientific mode provides access to various functions like trigonometry, logarithms, factorials, power, and square roots.

Trigonometric Functions: You can calculate sine, cosine, tangent, and their inverses by clicking on the corresponding buttons.
Logarithms: Get logarithms with base 10 ("log") or natural logarithms ("ln") by clicking on the respective buttons.
Factorial: Calculate the factorial of a number using the "!" button.
Power and Square Roots: Use the "x^2" button to square a number and "√x" to calculate its square root.

Using Programmer Mode

Windows Calculator also includes a Programmer mode for working with binary, octal, decimal, and hexadecimal numbers. Here's how to use it:

Switch to Programmer Mode: Click on the "View" menu and select "Programmer".
Number Base Conversions: Programmer mode allows you to convert numbers between different bases. To do this, select the desired base (binary, octal, decimal, or hexadecimal), and enter the number you want to convert.
Bitwise Operations: The Programmer mode also includes bitwise operations like AND, OR, XOR, and NOT. Use the respective buttons to perform these operations on binary numbers.

Using Date Calculation Mode

In Windows Calculator, you can easily calculate the difference between two dates using the Date Calculation mode:

Switch to Date Calculation Mode: Make sure you're in Standard mode, click on "View", and select "Date Calculation".
Inputting Dates: Enter the start and end dates in the desired format (e.g., mm/dd/yyyy). You can also use the calendar button to select dates visually.
Calculating the Difference: After entering the dates, the Calculator will display the difference in years, months, and days.
