==Module Information==

This is effectively meant to be the third puzzle. The idea is to teach the player how to use the subtract command. This will likely be the first time the player will have to think about the shortcomings of the TIS-100 having only 1 register per node that offers direct access for storage and retrieval of variable values. As such, the user will have to think about how to utilize the other nodes as direct access registers with "extra steps."
