Binary Calculator
Add, subtract, multiply or divide two binary numbers.
Binary arithmetic follows the same rules as decimal arithmetic, just in base 2 — this handles addition, subtraction, multiplication, and division directly on binary numbers.
Why binary matters beyond computer science class
Every digital system ultimately represents data in binary — understanding binary arithmetic is foundational for anyone working with low-level programming, digital logic, networking (subnet math), or computer architecture.
Frequently asked questions
Can I enter numbers that aren't just 0s and 1s?
No — valid binary numbers only contain 0 and 1 digits; any other character will produce an invalid result.
Why does binary subtraction sometimes give unexpected results?
If the result would be negative, standard unsigned binary subtraction can produce unexpected values — this calculator handles it using standard integer math and displays a normal signed result.
