Foreigners don't have China's multiplication table, so how do they calculate multiplication?

China's multiplication table is memorized by everyone, so it is very convenient to calculate. Children and adults come with their mouths open. It is convenient to calculate the multiplication of low digits. Then foreign countries also have their own calculation methods. Then let me talk about it.

Foreigners calculate multiplication by drawing lines. In fact, it is to solve arithmetic problems by drawing pictures. For example. For example, 12x 1 1. First draw a vertical line on the number to represent the number 10, and then draw two vertical lines to represent the number 2, which means 12. Then draw two horizontal lines to represent the number 1 1. Then start looking for the intersection of these lines. This point should be cooked from the lower right corner and the intersection point should be from the lower right corner to the lower left corner. The units of measurement are 10, 100, 100, 1000, 10000. Painting is like drawing gobang. This is a way for foreigners to calculate by hand.

In fact, this method is awesome at first glance, but it is not as convenient as China's multiplication formula. This method is not very common in foreign countries, after all, there are computers now, and foreigners usually use computers to solve the calculation.

So in fact, the calculation ability of foreigners is not as high as that of our country. For example, if you go to a convenience store to buy something, the salesman may tell you the total amount at once, but in foreign countries, even if you buy something with 12.73 yuan, you give it to 20 yuan, and he will pick up the computer to calculate how much change you have for half a day. Therefore, foreigners' oral expression ability is relatively poor.

So if you live abroad for a period of time, you may be shocked by their computing power and be proud of your 99 multiplication table and other abilities.
