We started algebra this year. By that, I mean my son has begun learning algebra in school and I have learned how much* I have forgotten when he asked for help. So doing homework every night has pretty much been what I imagine the coliseum looked like in Ye Olde Days of Rome, minus the lions. But with crying and door slamming. (On my part) Anyway, a friend recommended this app and I am in love with it. So is my son. We burned through the ten free problems and then paid for the unlimited problem solving in the first week. I love how straightforward the solutions are. I love how easy the menu is to figure out, and how easy it is to switch between different types of math. And yes, kiddos, I love that it vibrates with every key touch. I dont need my spawn to learn how to cheat, I need him to learn how to do math so he can get a good job and pay for the fancy nursing home I know hes planning to dump me in someday. I love that its virtually impossible to use this app in class without being discovered. To be blunt, this is also the cheapest math help app that also actually helps. So get it. *all of it
