Illusion

@TSS-Graviser It's possible to learn math well and deeply without repetitive exercises that cover the same material ad infinitum! Once you have learned a concept and it has been moved to the "easy" pile of things you know, it's not essential to come back to it in order to practice. Instead, don't be scared to move on instead to something you don't have a good grasp of yet.

@debbie not just the easy questions and not only the hard ones.

@placidmacaw-0 Yes! That was a good question, and it wasn't easy or hard!

@placidmacaw-0 He's taking the U.S. team to the Romanian Master of Mathematics Competition, which they did not badly at last year!

Ooh yay thanks @debbie for the upvote.

@po Thanks for such a cool illusion! I never expected that A and B are the same. It’s amazing how our brain can trick us that much.
