Frequently Asked Questions

What is binary arithmetic?
Binary arithmetic follows the same rules as decimal arithmetic but uses only two digits — 0 and 1 — operating in base 2. Computers use binary internally for all calculations.
How do I convert a decimal number to binary?
Divide the decimal number repeatedly by 2, recording the remainder each time. Read the remainders from bottom to top to get the binary representation.
Can I use this tool for bitwise operations?
The calculator focuses on arithmetic (add, subtract, multiply, divide). For bitwise AND, OR, XOR, and NOT, use the Hex Calculator which supports those operations.
