What is the term of eliminating division?
Split term elimination method is to decompose each term (general term) in a series, then recombine and eliminate some terms, and finally achieve the purpose of summation. For example,1[n (n+1)] = (1/n)-[1(n+1)],1[(2n-/kloc)

This deformation is characterized by the fact that after each item in the original series is split into two items, most of the items in the middle cancel each other out. There are only a few things left. The remaining items have the following characteristics, and the positions of the remaining items are symmetrical. The positivity and negativity of other projects are opposite.

Mathematical algorithm rules

When it comes to mathematics, parents generally have two misunderstandings. One is to simply think that mathematics is equal to operation, so that children can learn mental arithmetic. In addition to faster calculation, children actually have no real mathematical ability. The other is to pay too much attention to it and send the children directly to learn Olympic mathematics. As a result, the children found it difficult, but they began to get tired of math. In fact, the key of mathematics lies in the cultivation of number sense and logical thinking ability.

Why don't children like math? Math should be fun, why don't children like it? In fact, my parents themselves are very resistant to mathematics, which should be attributed to the shadow brought by their complicated calculations at school. And this misunderstanding of mathematics is used by you on children.

For example, letting children entangle all kinds of addition and subtraction from an early age, reciting multiplication formulas, and even taking Olympic math classes will make children feel frustrated. Mathematics should cultivate mathematical sense and logical thinking ability. Sense of number is sense of number, which refers to a person's ability to understand and use numbers, including whether he can handle numbers and disassemble numbers flexibly and look at problems from different angles.

The cultivation of logical thinking ability can help children calmly face and solve various problems in the future and become the people needed by the future world. This is the best gift that mathematics can bring to children.
