Answer the questions correctly to move on! There are only three levels for addition and three levels for subtraction. Three questions per level. You can learn different math strategies along the way to help you too! The "say something random" thing when picking addition or subtraction thing will make sense once you complete everything. (By the way, feel free to have some SCRATCH paper handy if you want to solve some of the bigger problems.)
I have finished endless modes!! If there are any bugs or glitches, tell me in the comments (or in person). Never click a character more than once. If you do, it will glitch out and to fix it you will have to press the green flag and restart. (Also, the multiplication and division features aren't working right now, so if you tap them, they will just disappear.)
