This holiday, I read the classic math series of horror science. It tells the mystery of mathematics in an interesting form. Although it is called "terrible science", it is not terrible. There are short stories in it, which can be mastered and understood without profound knowledge. From the "Terrible Science-Classic Mathematics Series", we can know that mathematics is no longer cold-blooded without emotion, and there are some seemingly simple tricks that can be used for a lifetime if learned.

One of them is called Fatal Mathematics, which tells one short and exciting story after another. Just like the story told at the beginning of this book-1One night in April, 927, in a restaurant on the main street of Chicago, the largest gangster old university in the United States couldn't do math, but didn't want to split the meal 50-50, so it had a fight with others, and all of them died in several gunshots. Listen, whether you are arguing about restaurant bills, studying how to launch rockets to the moon, or maybe you just want to do a few tricks for your friends, you need to know some math-deadly math knowledge!

There is another story. On your birthday, you want to share this cake with your six friends. So how much can everyone get by sharing this cake equally? This is a mathematical problem that needs to be solved. In principle, we can understand that 1 cake is divided among seven people. At this time, a friend of yours who likes to show off with a calculator, but obviously not smart enough, immediately took out his calculator, pressed "1.477", and then said without thinking, "This is too simple, and each of us should get 0. 142857 143 of the cake." Is this ridiculous? Who can imagine the concept of a cake 0. 142857 143? In order to punish this idiot who thinks that the calculator can solve everything, put him in the cupboard and let six people share it equally. Can you imagine what a sixth of the cake looks like? It's simple. Just cut the cake into six equal parts, one sixth each. You don't need to deal with any complicated calculations in your head, just divide the cake equally.

Therefore, calculators are not omnipotent. Its biggest problem is that it is not good at expressing scores and solving mathematical problems in life. This also requires us to learn and use them flexibly. I will learn math well in the future.

There are many stories in this book, and each story is so interesting.

the second

Horror science is a set of classic mathematics books, which contains inevitable strange circles-circles and other figures. Can you really+-××× find the secret of your lucky star-probability? Algebraic Ren Woxing, desperate fractions, measurement and measurement-length, area and volume, etc.

When it comes to mathematics, most people think it must be profound and difficult to understand, but this set of books is not. It shows you mathematics in the form of interesting stories, which makes people suddenly realize, "Oh, so that's it!" Of course, it also exercises you to learn to think independently, and also tells you some tips, shortcuts and clever tips for learning mathematics. Although this book is called "Terrible Science", it is not terrible in itself, on the contrary, it is very interesting.

At first, I found it difficult. Then slowly, I understood and fell in love with this set of books. Whenever I read it, I can't help being taken to the wonderful kingdom of mathematics and feeling the wonder of mathematics. Every time I close a book, it's a memory. At this time, I always think of some unsolved problems I have encountered before. Now, if I think clearly according to the methods in the book, I can solve them at once.

"Horrible Science" tells me that mathematics is actually very interesting. As long as you relax, think seriously or think from another angle, you will get the answer. It also made me realize how important mathematics is. It is a good helper in our life and helps us solve various problems. Without math, our life would be in chaos!

I like scary science!
