Binary Number Subtraction Calculator

 Minuend:
Subtrahend:
 
Complement:
2's Complement:
Result:

To perform binary subtraction you can use either the carry method commonly used with decimal numbers, or you can use the 2's complement method commonly performed by computers. With the 2's complement method, rather than subtract, you add the 2's complement of the subtrahend. This calculator not only uses the 2's complement method but also, for educational purposes, displays the complement and 2's complement of the subtrahend.

Note: I have (arbitrarily) limited the input binary numbers to 12 digits. If you would like me to modify it to accept longer binary numbers, please contact me via this site's contact form.

JavaScript: A Beginner's Guide shows how to create dynamic Web pages complete with special effects using today's leading Web development language. With the growth of HTML 5, JavaScript is expected to grow even more to script the canvas element, add drag and drop functionality, and more. This fast-paced tutorial provides step-by-step coverage of the fundamentals, including variables, functions, operators, event handlers, objects, arrays, strings, and forms. The book then moves to more advanced techniques, including debugging, accessibility, and security. This pedagogically rich, hands-on guide explains how JavaScript works with HTML 5 and covers the new features available in JavaScript.
