other either blue or green, depending on their status.)theorems contains the number of theorems (not axioms) that were invented by the user. proofs shows how many proofs were done, for a completed project this is equal to
the number of theorems. proof steps shows the number of rule applications of the calculus. interactions is the number rule applications that were done by the user.
