previous situation review
on August 29, the reporter found that the Construction Bank app has added two submenus of "digital wallet recharge" and "digital currency"

at the end of 2013, the central bank and other five ministries jointly issued the bitcoin risk notice, which clearly defined bitcoin as a special Internet commodity, but denied its monetary attribute According to the notice, at this stage, financial institutions and Payment institutions shall not price procts or services with bitcoin, buy or sell bitcoin or act as central counterparties, underwrite insurance business related to bitcoin or include bitcoin into the scope of insurance liability, or directly or indirectly provide customers with other services related to bitcoin, Including: providing bitcoin registration, trading, clearing, settlement and other services for customers; Accept bitcoin or use bitcoin as a payment and settlement tool; Carry out bitcoin and RMB and foreign currency exchange services; Carry out bitcoin storage, custody, mortgage and other services; Issuing financial procts related to bitcoin; Take bitcoin as the investment target of trust, fund, etc
as a financial institution, it is impossible for banks to provide virtual currency exchange services. But virtual currency can be traded on the trading platform in China. For example, Fuyuan currency can be traded on the Fuyuan currency trading platform, and bitcoin can be traded on the bitcoin trading platform.
The even ten method is to divide the subtracted number into two numbers. The subtracted number should be equal to 10 after subtracting the first number, and then use 10 to subtract the second number to get the final result
for example, in the calculation of 9 + 7, we should first divide 7 into 1 and 6, because 9 is short of 1, so we need to divide 1 out of 7. Therefore, 9 + 7 should be calculated in two steps, 9 + 1 = 10 and 10 + 6 = 16, and finally 9 + 7 = 16
Therefore, we should remember the pithy formula of "9 to 1", "8 to 2", "7 to 3", "6 to 4" and "5 to 5"
{rrrrrrr}
the addition and subtraction operation within 20 is one of the most important contents of grade one mathematics. The operation will use the four operation methods, which are rounding ten method, breaking ten method, leveling ten method and borrowing ten method. The most commonly used are rounding ten method and breaking ten method
When doing operations within 20, we should pay attention to the following two problems Abdication subtraction: we should keep in mind that we should start from the indivial position first; Which is not enough to retreat from the front, do not forget the standard plus ten; If the interval goes back by 1, 0 is the best one to remember Continuous abdication subtraction: see 0, move forward, and see which one has it; I borrowed it and went back. 0 is a bit like 9Even ten method: it is used to calculate the abdication subtraction within 20. One method is to divide the number to be subtracted into two numbers. The subtracted number should be equal to 10 after subtracting the first number, and then use 10 to subtract the second number to get the final result
The following figure can better show the flat ten method:
for example, 15-8 = 7 can divide 8 into 5 and 3, so the integral can be divided into 15-5 = 10 10-3 = 7
The algorithm of addition and subtraction is as follows:1. Integers: align the same digits, count from one digit, count from tens to one digit in addition; If there is not enough subtraction in subtraction, it will be subtracted by 1 from the higher digit, and then subtracted after adding 10 and the local digit
2 decimal: decimal point alignment (i.e. same digit alignment); Calculate according to the rule of integer addition and subtraction; Align the decimal point on the horizontal line and the decimal point on the point
The denominator is not changed, only the numerator is added and subtracted; In addition and subtraction of fractions with different denominators, the general score is given first, and then it is calculated according to the rule of addition and subtraction of fractions with the same denominator; If the result is not the minimalist score, the offer is divided into the minimalist scoreFlat ten method
15-8 =? We can do this by subtracting 5 from 15, leaving 10, and then subtracting 3
The basic principle is to regard 15 as a 10 and a 5, subtract 5 first, and then move our 10from the diagram, it is easier to understand some
