Great for adults not in school, but not for kids supposed to be learning math.

This app is great for those NOT in school and are adults. It's perfect for when you can't remember how to figure fractions and need to know for a recipe. However... This should NEVER be given to kids or be allowed to be on their phones and iPads. Kids are not doing homework when they use these apps. All they will do is point and click and do not do their own thinking and work. Some kids may be very honest and do their OWN work, but I know for a fact that many do not do their own work and cheat using calculators. That is disgusting! Teachers are now requiring calculators for 6th graders. Excuse me, these kids are not college students. DO YOUR OWN WORK and NOT with a calculator. Teachers are making kids stupid and math illiterate when they let them use calculators this early in school.
Teachers are NOT teaching when they are allowing kids to point and click on calculators. They do not use their brains. They use FINGERS. Their brains are empty and not learning math when they use calculators. Anyone who is smart will realize this. Do not let kids check their work with this app. They should be learning to use their brains and know how to check their work using MATH and not their fingers.

These apps have their place and that place is not for doing homework. Great app however, when used for the right purpose!

Great app

I personally learn a lot of new concepts in math and forget the simplest math problems and how they are supposed to be solved, although I do believe kids should be doing work themselves these days I also think this is a great app for students who can’t remember their fractions. 6th graders are now required calculators so why not have it as an app. I’ve seen some people review that the app should not be allowed for little kids and that 6th graders should not have calculators but at the same time, 6th graders are given many extra math pages and learn new concepts and laws of math every day. I do believe that kids shouldn’t resolve to an app when they can’t remember their fractions or what not but considering the fact that 6th grade is a bridge year and the teachers have to teach them new concepts everyday I think this app is amazing.

Great for school!

My math teacher has us doing complex fraction work and this really comes in hand for us! She hates to see us have a cluttered paper and complains about it all the time and this makes homework go by easily in the recommended 15 minutes. And to the reviews that claim it’s making us stupid, we have over 30 to 50 questions a night so go complain somewhere else, maybe if you had children you’d understand that you wouldn’t them spending 2 hours on math because of our teachers and their limitations.
