About this interactive
What you're seeing: a drill that pairs two binary numbers and asks you to add them, one question at a time. Why it matters: binary addition is the core operation inside every ALU — every calculation your CPU makes starts here. How to use it: you'll be given two binary addends and asked to enter their sum in binary yourself, with immediate feedback on whether your answer is correct.
What you'll learn
- Add two binary numbers and express the result in binary, applying carry rules across each bit position.

Key terms
- Binary
- The base-2 number system that uses only the digits 0 and 1; the native language of digital computers, which store and process data as electrical on/off states.
- Bit
- Short for binary digit, the smallest unit of data in computing, holding a single value of 0 or 1; all digital information is ultimately composed of bits.
- Carry
- In binary addition, the value of 1 passed to the next higher bit position when a column's sum exceeds the maximum value representable by a single bit.
