This tool lets you effortlessly perform basic arithmetic calculations on an easy-to-use 8×8 grid.
How to Use the Calculator
This calculator allows for basic arithmetic operations including addition, subtraction, multiplication, division, and the use of parentheses for grouping. To use the calculator, simply click on the buttons to construct your arithmetic expression, and then press the ‘Calculate’ button to see the result.
Explanation of How It Works
The calculator works by appending the clicked numbers and operations to a string called ‘expression’. When ‘Calculate’ is pressed, this expression is evaluated using JavaScript’s eval() function. The result is then displayed in the input field labeled ‘Result’.
Limitations
Please note that the use of eval() can be dangerous if not handled properly as it can execute arbitrary code. This implementation does not handle all possible errors or security vulnerabilities related to the use of eval(). Use this calculator for simple arithmetic operations only.
