① What is the problem?

How does a computer store information using only 0s and 1s?

② How does a classical computer approach it?

Each bit is a switch that is definitely 0 or definitely 1. Many bits together encode numbers, letters and pictures.

③ How does the quantum approach differ?

A qubit can hold a superposition — but measuring it still gives one bit. This experiment builds the classical baseline first.

④ What is happening mathematically?
n bits have 2ⁿ possible patterns. The pattern bₙ₋₁…b₁b₀ represents the number Σ bᵢ·2ⁱ.
⑤ What does the simulation show?
Each bit flipping between 0 and 1, the decimal value, and how the number of combinations doubles for every extra bit.
⑥ What did we learn?
Adding one bit doubles the number of patterns. A classical register holds exactly one pattern at a time.
⑦ What can you experiment with?
Use 4 bits and count up from 0000 to 1111. How many steps did it take? Predict the count for 8 bits.
