Example Data Table

Example	First Number	Second Number	Sum	Difference	Product	Quotient
Set 1	12	3	15	9	36	4
Set 2	8.5	2	10.5	6.5	17	4.25
Set 3	-6	4	-2	-10	-24	-1.5
Set 4	25	0	25	25	0	Undefined

Formula Used

Sum: Sum = a + b

Difference: Difference = a - b

Product: Product = a × b

Quotient: Quotient = a ÷ b, where b ≠ 0

This calculator evaluates two numbers with four core arithmetic operations. Division by zero is not allowed, so the quotient becomes undefined when the second number equals zero.

Frequently Asked Questions

1. What does this calculator do?

It computes the sum, difference, product, and quotient for two entered numbers. You can also run one operation only and control decimal precision for the displayed results.

2. What happens when the second number is zero?

The quotient becomes undefined because division by zero is mathematically invalid. The calculator still returns the sum, difference, and product normally.

3. Can I use decimal and negative numbers?

Yes. The calculator accepts positive numbers, negative numbers, and decimals. This makes it useful for basic arithmetic checks, classroom practice, and quick verification tasks.

4. Why is decimal precision included?

Decimal precision controls how many places appear after the decimal point. It helps keep outputs clean, consistent, and easier to compare in reports or study notes.

5. What does the graph show?

The graph visualizes the calculated outputs. It helps you compare the magnitude of the sum, difference, product, and quotient using a quick bar view.

6. What is included in the CSV export?

The CSV export includes input values, the selected mode, and each visible result. It is useful for spreadsheets, archives, and sharing numeric outputs.

7. What is included in the PDF export?

The PDF export creates a compact summary of the current calculation. It lists the input values and the generated arithmetic results in a printable format.

8. Is this useful for learning arithmetic?

Yes. The calculator shows direct operation steps, result cards, and a comparison graph. These features support quick checking, self-practice, and classroom demonstrations.
