1. Divide the integer part of the square root from single digits to the left, and divide every two digits into several segments, representing how many square roots there are.
2. According to the number in the first paragraph on the left, find the number with the highest square root.
3. Subtract the square of the highest digit from the number in the first paragraph, and write the first remainder of the number in the second paragraph on the right side of the difference.
4. Multiply the highest bit by 20, and try to divide the first remainder, and the largest integer is the trial quotient.
5. Multiply this quotient by 20 times the highest digit of the quotient, and then multiply it by the quotient.
6. In the same way, continue to find the square root of other digits.
For simple integers, it can be solved directly. For complex non-integers, approximate methods or special calculation tools are needed. Understanding the concepts of square root and square operation is also the basis of square root. It should be noted that the prescribing party usually gets two kinds of results (positive and negative), which are called primary and secondary parties respectively.
For example, √ 4 = 2. But in practical application, only non-negative results are usually considered. In addition, we need to distinguish the concepts of square and root. Square refers to a number multiplied by itself, such as a? = a× a. To find the root is to find the square root of a number.
The benefits of learning mathematics
People who are good at math are relatively smart and savvy, and they can show their advantages in dealing with people. The faster you think, the more ways and ideas you have. Cambridge, majoring in financial mathematics at Carnegie Mellon University in the United States, said that studying mathematics has brought her mental exercise and made me pay more attention to the rigor of thinking in my life.
For example, before solving a problem, I like to divide it into several sections, and each section is divided into several steps, so that I can dig slowly like a branch instead of thinking in confusion in front of a pile of data.
