Good job alex! it's very nice how you put down the divisibility rules, but maybe try adding a picture and some examples next time. keep it up! :)

good job alex....its good how you put in the divisibilty rules and circle formulas.....a suggestion is to add a photo or a video....But other than that it was good

Good job, Alex. You got the information down for sure but it's quite mixed so I couldn't tell if they're together or not but the information helps!
