Welcome to the Calculator Lite! This calculator provides a range of functions for basic arithmetic operations, including addition, subtraction, multiplication, and division. Additionally, you can perform square, square root, and change sign operations. This calculator showcases front-end development skills using HTML, CSS, and JavaScript. The project adheres to MVC (Model-View-Controller) principles, demonstrating a structured architecture without relying on additional modules.
The primary goal of this project is to highlight proficiency in front-end technologies, emphasizing:
HTML: Used to structure the content and layout of the calculator.
CSS: Handles styling and design elements, ensuring a visually appealing and user-friendly interface.
JavaScript: Powers the interactivity and functionality of the calculator, incorporating MVC principles for a clean and organized codebase.
Addition (+): Add numbers together for simple arithmetic.
Subtraction (-): Subtract one number from another.
Multiplication (x): Multiply two numbers to get the result.
Division (/): Divide one number by another.
Square (x²): Square a number, multiplying it by itself.
Square Root (√): Find the square root of a number.
Change Sign (+/-): Switch between positive and negative values.
History Tracking: View a record of your calculation.
Clear Last (C): Delete the last entered symbol or operation. If the last operation was '=', it removes the history.
Clear All (CA): Delete everything, including the current number.
Repeated Equals (=): Pressing '=' multiple times consecutively will repeat the last operation.
If you press the '=' button multiple times consecutively, the calculator will repeat the last operation. This feature allows for quick calculations without re-entering the entire expression.
- To calculate 10 + 5, press '10', '+', '5', and '=', resulting in '15'.
- To perform consecutive calculations like 10 + 5 + 5 + 5, continue pressing '=' two more times, resulting in '25'.
- To find the square root of 25, press '5', and '√', resulting in '5'. Press '√' again to get '2.236067977'.
-
Numeric Buttons: Use the numeric buttons to enter numbers.
-
Operation Buttons: Select the operation you want to perform (+, -, x, /, x², √, +/-).
-
(Optional) Enter second number using buttons.
-
Clear Last (C) Button: You can change number or operation by deleting with 'C' button.
-
Change Sign (+/-) Button: Switch between positive and negative values.
-
Equals (=) Button: Press the '=' button to calculate the result.
-
Clear All (CA) Button: Delete everything to beging new chain of calculations.
