Hello! Your spirit of studying hard and learning with an open mind deeply shocked me, which also shows that you are excellent. I wish you better grades. I believe you will be a mathematician like Chen Jingrun when you grow up.

? I am a junior high school graduate who graduated from 1967. There are more than 50 students in three classes in the school/kloc-0, and only 4 students have been admitted. Luckily, I was admitted to the county key middle school. After entering junior high school, I only knew how to look up the math table, and I was curious about this short division box, so I taught myself this. Today, let's recall the last picture, which is A2+2ab+b2=(a+b)2.

Then calculate the root number 10.24 according to the above method.

Note: Take a summary for every two digits of the integer part, starting from the lowest digit. The decimal part begins with the highest digit, and every two digits are also used as a summary.

I answered 10 questions the day before yesterday, but five of them are still in the process of automatic submission. I was annoyed, but I was really moved by this student. In addition, I have the spirit of studying since I was a child and have a good foundation. So take this opportunity to answer.

In addition, I can't remember this short division now, and it is impossible to abstract it in concise mathematical language.

I use manual square root, can I give a satisfactory answer?
