Calculation force of decimal point addition and subtraction meth

1.

1) To calculate decimal addition and subtraction, first align the decimal point of each number (that is, align the number on the same digit),

2), then calculate according to the rule of integer addition and subtraction, and finally align the decimal point on the horizontal line in the number

summary: when calculating the decimal addition and subtraction method, the decimal points should be aligned, that is, the digits should be aligned

For example, Xiao Fang bought some apples and oranges in the supermarket, which cost 8.6 yuan for apples and 6.2 yuan for oranges. How much did he spend? 8.6 yuan is 8.6 Jiao, 6.2 yuan is 6.2 Jiao, 8 yuan + 6 yuan is 14 yuan, 6 yuan + 2 jiao is 8 Jiao, that is 14 yuan

So 8.6 + 6.2 is 14.8. Therefore, the decimal addition in the column vertical calculation, to align each digit, that is, the decimal point alignment. The subtraction of decimals is the same

2. First align the decimal point, and then calculate the decimal part, and the integer algorithm is the same. Then calculate the integral part, for example:
2.34
7.1
+
13.67

0.9

5. How can companies that are optimistic about going public in the U.S. apply for new U.S. stocks

first of all, U.S. stocks and A-shares are totally different ways of subscription. Having a U.S. stock account does not mean you can subscribe

if you want to apply for IPO shares, you should contact your securities company after you submit the F1 document or S1 document from the company. Generally speaking, your securities company will contact you. The roadshow is a promotion meeting for prospective subscribers. Pay attention to the difference between the securities companies and the IB you open an account with, which refers to the IPO underwriters of some listed companies such as Goldman Sachs, Merrill Lynch and UBS. You become an underwriter's client, submit the subscription requirements, you can. Of course, there will be certain restrictions on account qualification (such as account opening time and amount of funds)

IPO stocks in the United States are generally owned by clients of investment banks. Their brokerage service is full service, and the broker will call according to the importance of the client to him

theoretically, if the underwriter is Goldman Sachs, you can also apply if you are a client of Merrill Lynch, but if there are many people, which one is easier to apply:) to become a client of these first-line investment banks, the current general requirement is that your assets should start from $1 million, and some securities dealers such as China merchants can also apply, which seems to start from $200000, However, if you get popular equity subscription through these domestic securities companies, the possibility will be relatively low

the IPO application of US stocks starts from US $1 million. It can be said that this is not a game for retail investors:) in addition, US stocks do not have the rule of "new must earn", and Facebook has also broken the market, so you have to have a bottom in how much money you accept. Bottom line: U.S. IPOs have nothing to do with retail investors. Good IPO has long been given to big customers by securities companies. If retail investors really score IPO, they are mostly rotten stocks, waiting for breaking

as long as your broker gets shares and you are a big client of your broker, you may get IPO. For example, if you are a client of a small securities firm (less than 1 million assets, but not too small for a small securities firm), if your securities firm gets the stock, you may have a share. As for whether a small securities company can get shares, it depends on the relationship between the securities company and the underwriter and the popularity of the stock. Small securities companies may not be able to get stocks. For example, sometimes small securities companies just participate in underwriting and can get certain stocks

the last thing to add is called friends and relatives stock. That is, if you have a channel to know the internal management of a listed company, you can get some friends and relatives shares. Friends and relatives shares are not given free of charge, or you don't need to become a brokerage customer and the concept of 1 million subscription. Generally, 10000 shares are a unit, and you can rely on the relationship to get as much as you want!

7. Select 1080ti. Although it's second-hand, it won't affect your use, and it's cost-effective.

8. Theoretically, 1080ti is close to 2080, slightly stronger than 2070super, significantly stronger than 2070, slightly weaker than 2080super, significantly weaker than 2080ti
if 1050ti is taken as the 1.0 performance benchmark, 2070super is almost 3.81080ti is 4.02080 is 4.12080super is 4.32080ti is 4.8 without driver optimization
2070super at present, you can buy a sub flagship like Qicaihong ad OC for 3800 yuan. With the optimization of the new driver, it should be able to compete with 1080ti in some new games. However, 1080ti's 11g video memory is not comparable to 2070s, 2080280s. Therefore, for game players, if they have a new 1080ti, its price is 3500-4000. Second hand ones are less than 3500
however, besides playing games, there are other people who use the graphics card for other purposes. The legal version of C4d that we use in the later stage costs two or three thousand a year, which is too expensive for students. They can only use pirated graphics cards. However, pirated graphics cards do not support 20 series graphics cards at present, so they can either change the colorator or buy 10 series cards. So that's why some 10 cards are a little more expensive
so the conclusion is that compared with 10 series, the performance of 20 series card is not as obvious as that of 9 series across 10 series. In the past, 1070 can beat 980ti, but now 2080 can only compete with 1080ti. The price of 1080ti is directly determined by 2080. 2080 is so expensive, so 1080ti can come down.
