Since the first few months of school, I have a new understanding of mathematics.
Mathematics is actually a very interesting subject.
For example, the number "9": choose a two-digit number, reverse the order of ten digits and one digit, and finally subtract a large number from the number. The difference must be a multiple of 9. Such as: 72-27 = 45,59415.
There are also rules in mathematics learning, such as:1÷ 9 = 0.1…, 2÷9=0.22…, 3÷9=0.33…, and so on. The difference between them is 0. 165438. Another example is: 6×7=42, 6.6×6.7=44.22,
6.66×66.7=444.222, 6.666×666.7=4444.2222, etc.
Mathematics is also widely used in life. One day, my mother and I went to the market to buy food. When buying cabbage, a catty of Chinese cabbage was 0.45 yuan, and we bought 1 1 catty (2 trees). "4.95 yuan" I said first.
The salesman calculated and found that it was really 4.95 yuan, which was very surprising. Actually, I just used the multiplication and division method: 0.45×11= 0.45× (10+1) = 0.45×10+0 = 4.5+0.45.
Since then, my understanding of mathematics has become more and more profound.
Personally, I feel that mathematics is improved by doing problems.
The knowledge points in the book are actually very few and simple. After understanding and memorizing, you have to do a lot of questions.
Sometimes you can't work out a big question, and then look at the answer, you will find it is actually very simple, because you haven't done enough. Remember the knowledge points in the book, do the questions repeatedly, and then understand the answer step by step. After a long time, the result came up.
Of course, learning mathematics also has certain skills, that is, being good at understanding and thinking.
For example: 64x 125, because 8x 125= 1000, then 64x1000 = 8x8x1000 = 8000.
It shouldn't be difficult to master learning methods, study hard and learn math well.
