Understanding the Canon MP11dx Calculator Logic
The Canon MP11dx was a popular desktop calculator known for its straightforward functionality. This online calculator emulates its basic arithmetic capabilities, allowing you to perform addition, subtraction, multiplication, and division between two numbers.
Core Operations:
- Addition: Combines two numbers to find their sum. The formula is simply
A + B = Sum.
- Subtraction: Finds the difference between two numbers. The formula is
A - B = Difference.
- Multiplication: Calculates the product of two numbers. The formula is
A * B = Product.
- Division: Divides the first number by the second. The formula is
A / B = Quotient. Special care is taken to handle division by zero.
How the Calculator Works:
This calculator takes two numerical inputs and an operation selection. Based on the chosen operation, it applies the corresponding mathematical formula. The JavaScript code below handles fetching the input values, validating them, performing the calculation, and displaying the result. It ensures that only valid numbers are processed and prevents errors, such as attempting to divide by zero.
Use Cases:
This calculator is ideal for anyone needing to perform quick and basic arithmetic calculations, similar to what a physical desktop calculator like the Canon MP11dx would offer. This includes:
- Everyday calculations for personal finance.
- Quick estimations in various professional settings.
- Educational purposes for practicing fundamental math operations.
- Anyone familiar with the ease of use of traditional desktop calculators.

} else if (operator === "multiply") {

operationSymbol = "*";
} else if (operator === "divide") {
if (num2 === 0) {
resultDiv.textContent = "Error: Div by Zero";
resultDiv.style.color = "#dc3545";
resultLabelSpan.textContent = "Status";
return;
}
finalResult = num1 / num2;
operationSymbol = "/";
}
// Display the result
if (!isNaN(finalResult)) {
resultDiv.textContent = finalResult.toLocaleString(); // Use toLocaleString for better number formatting
resultLabelSpan.textContent = "Result of " + num1 + " " + operationSymbol + " " + num2;
}
