LG Optimus f3 (uninstalled) this is different than what I was looking for but different is good. I like the single digits and the grid layout. I like untimed practice mode. and I'm liking the limit of operations per answer. I do NOT like not getting a chance to correct mistakes or do-overs or "try again". correcting errors is how we improve. 5* with corrections and/or correct answer displayed longer. boo.
Good workout but could be even better The player should be able to see the correct answer after choosing the wrong expression to get the given number. This allows the player to have a more meaningful learning experience. Maybe you could stop the clock when the player goes back to review their incorrect answer (to see their mistake), then resume the timer for the next problem
Good & Can Get Better It is a good app, need lot of practice for a beginner like me. I hope to see more updates, improvement and features
Levels 2 & 3 really make you think especially with the clock ticking
Nonsense 2 numbers and one operator?
Fun Fun but could be better. Would be great to see a proposed solution when you skip or fail.
