The manga whose title is "Saving a Weak Nation by the Numbers!" This is a very interesting comic book.

# You can read this on Dad's Kindle > my daughters

I found that there is also a paperback version. I'm considering buying it.

As I've explained in my previous in "AI Series", this books include

- Game Theory

- Auction Theory

and, I am impressed by the very clear use cases in the story.

Also, "Holt-Winsters method" and "Lanchester's Law", which I have not known about, come to appear in the book.

I was reading the manga while looking these up on WikiPedia.

I've been vigilantly thinking about using the "Lanchester's Law" method of comparing forces in my columns.

At this age, I have finally come to understand the difference between "simple interest calculation" and "compound interest calculation".

(These are similar to the "consumer finance" and "Amway" stories we talked about before.)

-----

The consistent policy of this manga (library) is "thoroughgoing strategy for the weak".

If I were to put myself in my shoes. I could think,

""A lonely strategy" of a senior salaried engineer without any academic cliques, connections, etc."

I told you this before, too.

""Weak" is "strong" when I master it."

I learned a lot from this story.

So, to all the young people of Japan, the world's leading math-phobic nation.

If you are a "loner" and want to survive in the future, math is going to be a great weapon.
