How does binary subtraction work?

Binary subtraction is performed using the two's complement method. The subtrahend is converted to its two's complement (negative representation), and then addition is performed to get the result.

What is two's complement?

Two's complement is a method for representing negative numbers in binary. To get the two's complement, invert all bits and add 1.

Can I subtract numbers in different bases?

Yes, you can enter numbers in binary, decimal, or hexadecimal format. The calculator will automatically convert them and perform the subtraction in binary.
