Regular calculations help life planning to open Baidu or Google's homepage through a browser, and enter the corresponding calculation formula in the search box. The input of the calculation formula is exactly the same as the common calculator, such as * for multiplication, /for division, and so on. For example, today I took 20 yuan, spent 2 yuan on the bus, 7 yuan on meals, and 3 yuan on newspapers (Figure 1). Then enter "“20-2*2-7-3”, click the "Search” button to see the remaining amount of money immediately.

There is a calculation formula here, that is, (∑Ri/7)× 365/10000 copies & times; 100%, where Ri is the revenue per 10,000 of the most recent i-day calendar day. By querying the revenue per 10,000 in the last seven days, they were 1.5429, 1.5559, 1.5695, 1.5698, 1.5720, 1.5792 and 1.5960, respectively, and 10.89853 was obtained by summation calculation. Then replace the Ri in the formula with these numbers, and the resulting seven-day annualized rate of return is 5.7%, which is still higher than the one-year deposit rate (Figure 2).
