Math Interactive

什么时候有中文那就更好了

This is a great app. It helped me a lot on my math classes and exams. I recommend this app to anyone. This is a must have app.

I like it so much,thx

Had a problem with premium, and within a day they fixed it for me.

I like the clarity, the comprehensiveness, the good looking presentation. Thang Bui

Thank you for making this app. Keeps my skills fresh as an aging engineer. Now I use it to help my kids with school. Made well and works nice on my iPhone 8.

Do not spend your money on this app, it is basically one of those plastic review sheets. The only interactivity is the selection of a topic to be displayed. The descriptions are limited to a single example with a brief explanation and sometimes a proof, which has no value in this setting. More examples are needed showing different circumstances. There is no mention of sequences and series which is a very important algebra topic. If it was free I probably would have deleted it also. Too bad. It sounded good but you had to pay to find out how lacking it is. Free google searches yield far superior content.

The one star reviews are harsh, unyielding, and expect the app to be something it’s not. This app is a clean, spare, dictionary of math formulas and concepts. All the info in a clear, easy to find place. It assumes you’ve already learned the material, and need help remembering it. If you are not learning or haven’t already learned the concepts, this will not teach you. It is not a magic wand, it’s not a teacher, and it’s not going to make the math itself easier. It’s simply a library of information that’s easily accessible. Khan academy and other online tools are not this. They are online math lessons, this is not. For the people complaining about the price, it’s $3, far less than the cost of any book. The people who built it did an excellent job, and you’re able to test the app out for free. You don’t pay the money unless you decide the app works for you. If the app is not what you need, that doesn’t make it a 1 star app. The rating of apps is not about you.

You would do much better learning this information on Khan Academy, which covers all of the topics in this app with more detail and more examples.

This is a must for anyone who ever needs to solve a math problem.
