This tool helps you perform advanced mathematical calculations effortlessly.
How to use the Khan Academy Calculator
This calculator allows you to perform basic arithmetic operations (addition, subtraction, multiplication, and division) between two numbers.
Instructions:
- Enter the first number in the ‘First Number’ field.
- Enter the second number in the ‘Second Number’ field.
- Enter one of the following operators in the ‘Operator’ field: +, -, *, /.
- Click the ‘Calculate’ button to perform the operation.
How it calculates the results:
The script will first parse and validate the inputs to ensure they are numbers and the operator is one of the allowed symbols. If any of the inputs are invalid, it will display an error message. If all inputs are valid, it will perform the specified operation and display the result in a table.
Limitations:
- The calculator only supports basic arithmetic operations: addition, subtraction, multiplication, and division.
- Only one operation can be performed at a time.
- Both input numbers must be valid decimal numbers.
