Station D

Play with the $1 \leftarrow 4$ machine and the $1 \leftarrow 5$ machine.

What is the $1\leftarrow 4$ code for the number twenty-nine?

What is the $1\leftarrow 5$ code for the number twenty-nine?

Can you work backwards?

What number has $132$ as its code in a $1\leftarrow 4$ machine?

What number has $132$ as its code in a $1 \leftarrow 5$ machine?

Well done! Now you can either go to the next island or perhaps go to the Wild Exploration Station below.
