Frequently asked questions
How does binary addition work?
Same as decimal, but you carry when a column reaches 2 instead of 10. This tool handles the carries and shows the decimal check.
Can it convert binary to decimal?
Yes — every result is shown in both binary and decimal, so it doubles as a converter.
