Does division give a remainder?

Division returns the integer quotient (floor) of A ÷ B. To see remainders, use a modulo tool instead — this calculator focuses on whole-number binary arithmetic.

What is the difference between addition and bitwise OR?

Addition carries between bit positions, so 1 + 1 = 10. Bitwise OR has no carry — it sets each output bit if either input bit is 1, so 1 OR 1 = 1.

Are large binary numbers supported?

Yes — operands are parsed as arbitrary-precision integers, so long binary strings compute exactly with no overflow. Nothing is uploaded; it all runs in your browser.

Binary Arithmetic Calculator

Add, subtract, multiply, divide and bitwise on binary numbers.

Binary arithmetic calculator

Run arithmetic and bitwise operations on two binary numbers: add, subtract, multiply, divide (integer quotient), plus the bitwise AND, OR and XOR. Every result is shown simultaneously in binary, decimal and hexadecimal.

Operands are parsed with arbitrary-precision integers, so even long binary strings compute exactly without overflow — and the whole thing runs locally in your browser.
