Fun game! I think it'd make a great educational tool for learning math!

fun idea, maybe limit the number of item you can use each turn

Nice and simple addition game. Could be a fun educational tool or a more intense challenge with a bit more expansion :)

Good simple math experience, we could see it being used in primary schools and stuff, maybe add some gamification somehow, perhaps a time limit or a queue of people requesting a specific weight, similar to Overcooked orders 

Good simple math game. Maybe a timer would be interesting to take as a challenge!
Also, a "next level" button could be good to improve the pacing and not having to go back to the main menu.
