Anzan Expert Brazil L +4

"6 + 9" is easy for me, but for some reason, I need some time to calculate "7 + 9"...

Don't you have such combinations of numbers that feel a little more difficult for you?
For me, the author of this app, the combinations containing 8 or 9 were difficult.
I felt it also hard to calculate the total price of products every time I went shopping.

So, I decided to develop this app, considering my own training too, and I actually improved my addition skills to some degree already by testing this app again and again while I was developing it.
I'm sure you'll also improve your own skills as I did!

I hope you enjoy the app as well as improving your mental addition ability.

HOW TO USE

Numbers are displayed one by one at specified time intervals.
Add up those numbers in your mind.

There are 20 stages with a combination of 5 kinds of digits (1 to 5 digits) and 4 intervals (6, 3, 1 and 0.5 seconds).
The highest stage is 5 number of digits with 0.5-sec intervals.

and so on...
