Why do you have to pay attention to the number of thunder when choosing a number? Let's talk about how the "thunder split number" came from. A foreign mathematician named Caprija was caught in a violent storm during a trip. After the thunder and lightning, he saw a milestone on the side of the road, which was split in half by lightning, half engraved with 30 and the other half engraved with 25. At this time, Capri's mind suddenly found a wonderful mathematical relationship-30+25 = 55 55 2 = 3025. Add up the numbers that are divided into two halves, and then square them, which is exactly the original number. In addition, are there any other figures with this nature? People who are familiar with fast calculation soon found another number: 2025. 20+25=45 45^2=2025 。 According to the name of the first discoverer, this strange number was named "Capri addendum", also known as "Rapi number". There are many ways to search for this number, but the simplest way is to find it in multiples of 9 and 1 1. For example, 55 mentioned above is a multiple of 1 1, and 45 is a multiple of 9.

In fact, we often see this "thunder score" on the license plate number of some cars on the street now, which may not have been known before! For example, let's look for it. According to the method I mentioned above, such as Chongqing A7777, let's calculate, 7777 2 = 60481729 6048+1729 = 7777. And Chongqing X980 1, 3025, 2025, 980 1, 100 (these are all examples, no offense). In the future card selection, we should avoid unlucky things, whether it is true or not, and we should also pay attention to it. Whether it happens or not, since it comes out, we must prevent it!
