Review All Results
See the sum (addition), difference (subtraction), product (multiplication), and quotient (division) displayed along with mathematical properties.
Formula
Addition: Sum = a + b
Subtraction: Difference = a - b
Multiplication: Product = a × b
Division: Quotient = a ÷ b (if b ≠ 0)
Example 1: 15 + 8
Sum = 15 + 8 = 23
Two positive numbers added together
Example 2: 15 - 8
Difference = 15 - 8 = 7
Subtracting 8 from 15
Example 3: 15 × 8
Product = 15 × 8 = 120
Multiplying 15 by 8
Example 4: 15 ÷ 8
Quotient = 15 ÷ 8 = 1.875
Dividing 15 by 8

Frequently Asked Questions
What operations does this calculator perform?
This calculator performs all four basic arithmetic operations: addition (+), subtraction (-), multiplication (×), and division (÷) with a single calculation.
What happens if I divide by zero?
Division by zero is mathematically undefined. The calculator will show "Undefined" for the quotient when the second number is zero.
Can I use this calculator with negative numbers?
Yes! The calculator works with positive numbers, negative numbers, decimals, and any real numbers. For example, -15 + 8 = -7.
What are the commutative and associative properties?
Commutative: Order doesn't matter (a + b = b + a). Associative: Grouping doesn't matter ((a + b) + c = a + (b + c)). These properties are shown in the results.
Can I use decimals and fractions?
Yes! The calculator handles decimals automatically. For fractions, convert to decimals first (e.g., 1/2 = 0.5) or enter as decimal values directly.
Is this calculator suitable for children learning math?
Absolutely! This calculator helps students understand basic arithmetic operations, mathematical properties, and provides instant verification of their calculations.
