If you want to be able to input in the computer, then the computer must be equipped with a Word document. If you want to use a mobile phone for input, then the code mobile phone must have relevant input methods.
If we enter these symbols in the computer account, we can open the Word document first, then find the second button in the top bar, and click the Insert button to find the symbol mark on the far right. When we click on the symbol, we can see our commonly used characters, and the symbols circled in one, two and three are just below the symbol mark. If we want to find more numbers with circles, we can find them in the math options under the symbols.
If we input this symbol by mobile phone, then we can choose to download an input method. Personally, I suggest downloading Baidu input method. If you choose mathematics from the symbols of Baidu input method, you can choose the related circled numbers. In daily life, many symbols have been integrated into the symbol options of computer and mobile phone input methods. So when we input, we just need to open the relevant buttons, and we can easily find these symbols for input.
In addition, the function of input method is becoming more and more powerful. With the development of science and technology, input method can be used for many operations, not only in the basic function of input method, just as we have voice input method to input articles, which reduces our input time.
At the same time, the input method can also use big data to correct the characters that we may accidentally type wrong when typing. This can also greatly increase our input fault tolerance rate when typing or writing articles.
