# EXPLORATION 1: What are these machines actually doing?

Can you figure out what these machines are actually doing?

Why, in a $1\leftarrow 10$ machine, is the code for two hundred and seventy three "$273$"?

Are all the codes for numbers in a $1\leftarrow 10$ sure to be identical to how we normally write numbers?

If we can answer this question for the $1\leftarrow 10$ machine, then can we make sense of all the codes for a $1\leftarrow 2$ machine? What does the code $1101$ for the number thirteen mean?

**Comment**: Of course, we will answer these questions in the next island, **Insighto**, but it might be rewarding to think about these ideas questions on your own first!
