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 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.

Totally agree! Not for homework!


This is terrific, for adults.

I have no trouble with fractions, but due to the need to create an answer key for an out of print textbook... when I’m exhausted from math or simply double checking did I do this correctly, this is awesome.

I would honestly check a child or teen device frequently or better yet insist they SHOW their work. To be sure they are not cheating and robbing themselves of an education. On the other hand those who want to learn will choose to and those who don’t will find a way to cheat...
