Basic Calculator

This basic calculator performs six core arithmetic operations: addition, subtraction, multiplication, division, exponentiation, and modulo. Enter two numbers, select an operation, and see the result instantly. It also displays the sum, difference, and product of your two numbers simultaneously for quick reference.

How It Works

Each operation applies a standard mathematical function to your two input values (A and B):

• Addition: A + B
• Subtraction: A - B
• Multiplication: A x B
• Division: A / B (cannot divide by zero)
• Power: A^B (A raised to the power of B)
• Modulo: A % B (remainder after dividing A by B)

Results are rounded to 10 decimal places for precision.

Example

Key Factors to Keep in Mind

• Division by zero — the calculator will display an error; mathematically undefined
• Modulo by zero — also undefined and will return an error
• Large exponents — A^B can produce very large numbers; results beyond 10^15 may lose decimal precision
• Negative numbers — fully supported for all operations, including negative bases with exponents

Tips

1. Use the power operation to quickly compute compound growth: for example, 1.07^30 = 7.61, meaning $1 at 7% annual return becomes $7.61 after 30 years
2. The modulo operation is useful for checking divisibility — if A % B equals 0, then A is evenly divisible by B
3. The calculator shows sum, difference, and product simultaneously, so you can compare all three operations without switching
