I noticed some progress in the mental math.

Today is the second day in a row when I have a rate more than 50% in 3x3 multiplication. Yesterday it was 60% today is 70%.

Lately I felt that my memory often can hold a number accurately for relatively long period of time, while I do other intermediate calculations.

It sometimes feels like a miracle. I calculate a number and realize I almost forgot the previous one. Then I pull some number from my memory, add up with the latest result - and the answer is correct.

I also noticed today, that I have some difficulty doing mental math multiplication not at the computer. Just to multiply two 2-digit numbers standing on the street with my friend took a lot of time.

The problem as I see it is that the expression is visible all the time I'm trying to solve it. So I'll add an option to hide formula after showing it for say 5 seconds.

I also want to change number generator to exclude "easy" numbers, like those ending with 0. Because multiplying 123*610 is not a fair 3x3 multiplication.

Hi! Nice remark about hiding formula. Probably it would be useful to add sound or other noise while training. It may help to simulate real-life obstacles.

And it will help to concentrate anywhere, not only behind the monitor.

thx

Yep, hiding the expression increased the complexity of the exercise dramatically and it stimulates working memory much more now.

If you feel something more is to be changed, please feel free to contact me about it.
