nice! instant throwback to childhood watching Des Chiffres et des Lettres on TV a bit of feedback, can you make it so that if you type an operation on the first block of a line it takes the last result as the first item and fills the op as the second item? the thing that trips me up playing is thinking like: "50 plus 3 is 53, minus 7 is 46, times 3 is 138" so I'd type 5 + 3 - 7... i.e I press the operation right away instead of typing the last result before the op... oddly frustrating! and I keep on doing it over and over again! oh, and I second the request to clear the board, reloading just doesn't cut it: it's a full, slow enough RTT to the server that I type on all inputs to clear them up instead. plus when added to the home screen as a web app on iOS there's no way to reload except killing the app... a bit frustrating also!
