Designing a Turing Machine for Unary Number Addition

In this video, we explain how to design a Turing Machine to add two unary numbers.
Unary numbers are represented using 1’s, and addition is performed by simply concatenating the two unary strings, separated by a 0.

📌 Example:
111011 represents 3 + 2 in unary → Output: 11111 (i.e., 5 in unary)

🔧 What you’ll learn:

Representation of numbers in unary

Tape design and symbol conventions

Step-by-step state transition to perform addition

How Turing Machines process, erase the 0, and concatenate unary strings
