Mencal - Mental Math Tricks 应用的评论

A good one to start with

Been out of school for a little while and needed this

Love this app.

The keypad can include arrow keys to edit.

Good

To keep your brain in 4/3 πr ³

希望类似的心算可以放在一起

不错，题目很有趣味

You just have to devote time do the application and do examples over and over and over again. With time your master these exercises. Your mastery will save you a lot of time.

I suggest starring the ones you're most likely to need. The app taught me there are a lot more shortcuts to math than I expected.

Helps you understand math in a new way

I like it very much. It is helpful

cute and useful. nice app to kill time

Awesome methods to learn mind calculation.Now i am good in mind calculations after using this app.

Like at least one other reviewer, I don't think the app creator has a great grasp on English, which is understandable. English is a difficult language. That said, I think the app creator should vet the app with an English speaking person. Secondly, but more importantly, I tried one of the tricks 267x11 but could not reproduce the correct answer using the "trick". I end up with 3,117 using the trick. (Correct answer is 2,937). Maybe it's the language issue or maybe the trick is not correct. Either way, I love the CONCEPT just struggling with the execution.

Best math app out there love the new update keep it up guys.

I have to buy this app on iPad again?

Full of various ways to break down and solve a wide range of equations. Some of the explanations are a little hard to follow, but overall it's a pretty and useful app.

The app has a sound design and beautiful aesthetics. The method learning portion could use some work - like a counter somewhere with the answers correct/answers wrong, and the icons for switching towards practice could be a bit more obvious, but that doesn't really take away from it. The practice mode that includes all methods could indeed have an option to remove certain methods that are more complex - such as squaring numbers in the 400s - so the user could practice several methods that he's learned at once. As for the instructions, I think they are pretty clear and if read with enough attention, are simple to understand. Overall it's a pretty amazing app and it has lots of potential for math-loving people. I enjoy it quite a lot.

I think I understand the point but these problems are so confusing. You have to understand more than basic math to get this.

This is the best-looking app of this sort that I have seen (other than the choice of handwritten/chalkboard font for the numbers), but something tells me the appearance took precedence over the importance of utility. The instructions for methods are sometimes unclear, and not only because it looks as though the person who wrote it was not a native English-speaker. Sometimes crucial words are omitted. Sometimes it's just unclear what's being said. Additionally, it is my opinion that the app could use some expansion regarding how one is able to test oneself. Let the user test him- or herself incrementally with each step as they begin to understand it, or allow the user to include or omit the methods used in the testing portion. Otherwise, it requires the user to master and understand each kind of method before feeling they can challenge themselves effectively. Otherwise, this is a great app, and a beautiful one to boot. I'd love to use this more often if I could seem to have it work more in my favor as I learn and test myself with each method. It certainly had great potential, and I look forward to seeing how/if it changes in the future.

me being very bad at math, this app can help me in many wonderful ways, thank you!!! :)

Sólo pido una versión en español para poder recomendarla a mis estudiantes.

Very fun and useful

I found these tricks extremely useful in daily lives,as a college student,it gives me fresh light about fundamental calculations again !

there are some tricks that can be helpful but there are also example that make it to complicated and hard. for example 45+54=99 the app says to add 4+5=9 then 9*11=99 why the hell would I do that when I can clearly see lining up the numbers in my mind they will both be 9's. it get even crazier with 3 digit numbers, taking a simple 3'digit addition number and mixing multiplication and more addition, it just seams stupid to make it harder.

if you love math - you will love the app

Well done learning app. Nice interface and content.

I've definitely been enlightened after merely a few minutes usage of this app. Right now I've been captured by the unfathomably mesmerizing beauty of this app. Try it you won't regret.

Thanks.

It's a good app for both kids and sometimes even adults

Its a useful app for anyone who wants to know the numbers deeper.

Keep updating with more math tricks!

Impressed.

It's an educational app, and it seems to be helpful for students.

This app rocks!! Great for Math Team practice!
