About this interactive
What you're seeing: a guided walkthrough of binary addition, column by column, right to left. Why it matters: the carry rule is the one thing that trips almost everyone up the first time — this puts you inside it, one column at a time. How to use it: step through the columns in Guided mode setting the result and carry cells yourself, then switch to Solo to fill the whole result row without the hints.
What you'll learn
- Given two binary numbers, step through the addition process bit by bit — applying carry rules at each position — to arrive at the correct sum.

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.
- Place Value
- The weight assigned to a digit based on its position within a number; in binary, each position represents a successive power of 2 (1, 2, 4, 8, …), making position the key to decoding binary values.
