How does binary addition work?

Binary addition works similarly to decimal addition. You add bits from right to left, and when the sum is 2 or more, you write down the remainder (0 or 1) and carry 1 to the next position.

What happens when there is a carry?

When there is a carry, it is added to the next bit position. If there is a final carry after adding all bits, it may indicate an overflow if the result exceeds the bit length.

Can I add numbers in different bases?

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