Let's begin from training of mental arithmetic.

We provide you with a certain method.

Let's imagine an abacus in the head.

Supposing you do not understand the method of operating an abacus, you need to study the knowledge in advance.

For that purpose, you have to practice using an actual abacus.

Since it is not so difficult operation, everyone can understand it.

Next, let's carry out training which visualizes an abacus by imagination.

You will be afflicted by idle thoughts at first.

However, if you exercise 20 minutes or more every day, you can continue having the image of the abacus fixed in about two weeks.

It is petty only by floating the image.

Let's calculate simply.

Train the four fundamental processes of arithmetic of 1 figure first.

When getting used, make it develop with 2 figures and 3 figures.

If it is addition, you come do calculation of 5 figures in less than one month.

Thus, you can acquire "mental-arithmetic capability" by the efforts for one month.

Now, probably, there are little people who are thankful for mental-arithmetic capability, since the calculator has spread.

However, it is applicable to "memorization capability."

This will be one of the capability which prep students want to acquire very much.

A method is begun from imagining "a pure white notebook."

It will take about two weeks until an image is completely established like an abacus.

If you write a character suddenly, probably you will lose perseverance.

At first, let's draw a circle, a triangle, and that figure.

Let's write an easy memorandum, if an image is established.

It is a success if you can remember it on the next day.

Let's complicate the contents of a memorandum gradually.

Also attach the index and the page number, in order not to forget.

Whether a how far complicated note is imaginable has started your perseverance and efforts.

A success of that is more difficult than the case in an abacus.

Therefore, we cannot guarantee that it surely succeeds.

However, if you succeed in it, you can attach an index to it or can sort if needed.
