The video of the boss of a hotel in Anhui Province blindly typing a calculator became popular. How fast is his blind typing speed?

Calculators are now people's accounting tools. It should be said that it is essential for hotels, restaurants and some businesses to use calculators at the checkout counter. Just like in school, when we study accounting and are related to money, there will be calculators, and the computer is also very convenient. You can't take out your mobile phone during the exam, but the computer can. The data calculated by the calculator is much more accurate than your own, which saves money.

I once saw a video on the Internet: In Suzhou, Anhui Province, a restaurant owner used a calculator to blindly check out the bill for customers, and his hand speed was amazing. The guests who went to this restaurant that day said that it was the first time that he saw such a checkout boss without looking at the calculator, while talking about the price of the food, and he never looked down at the calculator in his hand, and his hand speed was amazing. After the boss calculated the bill, he calculated the bill for the customers, and the money was not bad. Later, the customer posted this video on the Internet, which attracted a lot of people's attention. The netizen said that he was the best in the line and gave his boss a big compliment. It was great and awesome. He must have been an accountant before. The customer also said that it was the first time he had seen such an account, which was really awesome. He who can play the calculator so skillfully is really a great man. In fact, I tried this skill a little blindly when I was in the training class in college, because I had to make accounts every day that week, and I had to make a summary of subjects after I finished it. I couldn't make any mistakes, and I had to press the calculator countless times every day, and the numbers were gone. But if you press it too much, you will find that you don't need to look at the calculator. The position of each number and symbol has been kept in mind. Just type it blindly. I've tried it several times myself, and I've never made a mistake, but I still have to look at it when I really summarize it. If something goes wrong, it's over. This calculator is just like a computer keyboard. If you practice more, you will be familiar with it, and your hand speed will be faster. Actually, it's the same with other things. Practice makes perfect. It doesn't matter if you can't do it well at first, but if you do more, you can do it well.
