It helped quite alot, I think the explanations of why an answer is wrong could be more clear. Mainly in fractions so far. That said, it has the rules and operations. It needs to remind you of them during exercises, but for free it is as good as any paid site. Thank you.

This is just what I was looking for. It's been years since I was last in school and Ive forgotten a lot of basic math. There are books at the library I can borrow, but there are very few that are combined with workbooks. This app is perfect for that. It teaches you how to do the operations and then you can practice the skill with this app. I really like this app.

would be nice as a free app with advertisements but unfortunately they lead you to believe that all you have to do is put up with advertisements just to have you hit a paywall eventually. (Update) I reached a point where I could not continue with the lessons unless I made a payment if that is not a paywall then I don't know what is !

Amazing app! its working for me. its levels, you have to get a current precentage to pass to the next level. or purchase a key to unlock it if you feel your ready. im trying to do that now and im having problems purchasing. it keeps saying error everytime i try.

It levels up as progress is made. I love this for my son. I have him utilizing this app as a game of encouragement. I tease him to say he's in 1st, etc grade not in 8th grade and that he can't get to his grade level. 😆 LOL. This upsets him to challenge himself ever more to reach his grade level to a higher grade level. 😂

Easy to use, with straight forward information, with lots of chances to quiz yourself after studying the material. It does have ads, but they are only 5 seconds long and pop-up at a tolerable rate.

Very simple explainations and easy to use. Practice tests let me use what I just learned at my own pace and give me the correct answers after taking. Great for studying on my breaks. Great app Do yall have a app for english and science also?
