How Does a Four Function Calculator Work?
At its core, a four function calculator operates through a series of electronic circuits and software that interpret user input and perform calculations. Here’s a basic overview of how it works:
1. Input: The user enters numbers and operations using the keypad.
2. Processing: The calculator’s microprocessor interprets the input. It uses algorithms to execute the specified mathematical operations.
3. Output: The result is displayed on the screen for the user to see.
Basic Operations Explained
Addition
Example: 5 + 3 = 8
When you input “5”, press the “+” key, then input “3” and press “=”. The calculator will display “8”.
Subtraction
Example: 10 – 4 = 6
Input “10”, press the “-” key, then input “4” and press “=”. The result displayed will be “6”.
Multiplication
Example: 7 × 6 = 42
Enter “7”, press the “×” key, then input “6” and press “=”. The output will be “42”.
Division
Example: 20 ÷ 4 = 5
Type “20”, press the “÷” key, then input “4” and press “=”. The calculator will show “5”.
