When it comes to performing mathematical calculations on a Windows environment, the built-in Calculator application is a handy tool. While the topic "Matemática" refers to mathematics in general, using Windows Calculator can help you perform various mathematical operations without needing third-party software.

Examples:

1. Basic Arithmetic Operations:

   • Open the Calculator by typing "Calculator" in the Windows search bar and pressing Enter.
   • Use the standard mode for basic operations like addition, subtraction, multiplication, and division. For example, to add two numbers, type 5 + 3 and press Enter to get the result 8.

2. Scientific Calculations:

   • Switch to Scientific mode by clicking on the menu (three horizontal lines) and selecting "Scientific".
   • You can now perform more complex operations like trigonometric functions, logarithms, and exponents. For example, to calculate the sine of 30 degrees, type sin(30) and press Enter to get the result 0.5.

3. Programming Calculations:

   • If you need to perform calculations related to programming, switch to Programmer mode.
   • This mode allows you to work with different numeral systems such as binary, octal, decimal, and hexadecimal. For instance, to convert the decimal number 15 to binary, type 15 and then click on the "Bin" button to get 1111.

4. Using Calculator via CMD:

   • While the Calculator itself cannot be directly operated via CMD, you can open it using the command prompt by typing calc and pressing Enter. This will launch the Calculator application.

5. Automating Calculations with PowerShell:

   • For automation or scripting purposes, PowerShell can be used to perform calculations. For example, to perform a simple addition, open PowerShell and type:

     $result = 5 + 3
     Write-Output $result

   • This will output 8, demonstrating how you can use PowerShell for mathematical operations.
