How it works
Enter two binary numbers and choose an operation. The tool converts them to integers, performs the arithmetic exactly using big-integer math, and shows the result in binary, decimal, and hexadecimal so you can check your work across bases. It validates that the inputs contain only 0s and 1s. This is useful for learning binary arithmetic and for low-level programming. All computation runs locally in your browser.
1010 + 0110 = 10000 (10 + 6 = 16)
Common use cases
- Checking a binary addition or subtraction by hand.
- Learning how binary arithmetic carries and borrows.
- Converting the result across binary, decimal, and hex.
Frequently asked questions
What operations are supported?
Addition, subtraction, multiplication, and integer division of two binary numbers. Division shows the quotient; subtraction can produce a negative result, shown with a sign.
Does it handle large binary numbers?
Yes. It uses big-integer arithmetic, so long binary strings are computed exactly without overflow.
Why show decimal and hex too?
Seeing the same result in three bases helps verify it and is convenient for programming, where hex is a compact way to read binary values.
