Want a no multiple choice option

This is a great app, but I wish there was a way to turn off the multiple choice option so one could enter the answer in a text field and see if their answer is correct. I'm aware there's an option to hide the multiple choice answers first, but it seems to me that while the multiple choice option would be beneficial in the beginning while learning the methods, it might be more useful and more challenging to be able to enter your own answer. I've been looking for an app like this, and this one is the best I've found, but I would like to see that one feature if it is ever at all possible.

Would not recommend...

...this app to be purchased to help with math. It is basically just teaches shortcuts to learn difficult math problems. This app gives students a procedural understanding for how to do certain math problems. Although certain math procedures may be used to solve the difficult math problems, these are all just short cuts. By having the student learn to actually solve the difficult problem would be much more beneficial for the student because it will help the student develop a conceptual understanding instead of just learning a shortcut to solve the problem. Only way this app could be beneficial is to get students to think about why these certain shortcuts work. But they would need to have a conceptual understanding of how to solve the problem on their own before they could do that.

Outstanding!

This app is awesome! I've had the book since long before the world went digital and it's great to see it in this format. I've introduced it to my 10-year-old as a quick way to double check her work as she has to write out her answers longhand for the teacher. I recommend this for anyone who doesn't want to always have to rely on a calculator.

One thing that would make it better though is to be able to turn off the multiple-choice answers and allow you to write in your answer.
