In #Paris, you can learn or review major equations on the wall while waiting for the #subway... Is it the new street art ? https://octodon.social/media/DN-UL4j4c2HBFMI6fFc
@xtof54 are there also the proofs printed?
@PiSquare Sure ! :-) But they're so long that they start in the subway and you have to follow them down to the catacombs under Paris...
