# 3-digit-basic-calc — interactive demo

Watch a **1.6M-parameter** from-scratch transformer do 3-digit arithmetic by
generating an explicit scratchpad, one step at a time. Type an expression like
`842/37` or `213*145` and see both the answer and the model's actual reasoning.

The model (`vmal/3-digit-basic-calc`) is loaded with `trust_remote_code=True`.
