1. Landlord, good, expensive. What's in bitland? It sells well all over the world< br />(*^__^*) Hee hee

In addition and subtraction of fractions with different denominators, we should first divide the fractions into the same denominator fractions, and then calculate them according to the method of addition and subtraction of fractions with the same denominator

In addition and subtraction of scores, the first step is to examine the questions and observe whether the scores have the same denominator or different denominator. If it is the addition and subtraction of different denominator fractions, it is necessary to carry out the general division first, and then the addition and subtraction operation. The final calculation result can be reced into the simplest score, the result is false score to be converted into a fraction or integer

When there are no brackets, the mixed operation of fraction addition and subtraction is carried out from left to right; If there are brackets, first calculate the one inside the brackets, and then calculate the one outside the brackets

Such as: 1 / 3 + 1 / 4 = 4 / 12 + 3 / 12 = 7 / 12

extended data

1, the greatest common factor of denominator is 1, the numerator is the sum of fractions of 1, the denominator is the proct of two denominators, the numerator is the sum of two denominators. The greatest common factor of the denominator is 1. The numerator is the proct of the two denominators by subtracting the fractions of 1. The numerator is the difference between the two denominators

The greater the difference between denominator and numerator, the closer the fraction is to 0; If the numerator is close to half of the denominator, the fraction is close to half; The closer the denominator is, the closer the fraction is to 1

3. The mixed operation order of fractional addition and subtraction is the same as that of integer and decimal addition and subtraction. There is no parenthesis, from left to right, operation in turn; There are parentheses. First calculate the formula in the parentheses

4. The operation law of integer addition and the operation property of integer subtraction can also be used in fractional addition and subtraction, making the calculation simple. The law of multiplicative distribution is also suitable for the simple calculation of fractions

3. In addition and subtraction method of different denominator fraction, the different denominator is divided into the same denominator, and then the numerator is added and subtracted.

4. The simplest way is to multiply the two denominators to get a number, take this number as the denominator, multiply the numerator of the two fractions by the denominator of the other fraction, and then perform the operation
for example,
x / y
-
n / M = (XM NY) / my
after calculation, you can rece the score
4 / 5-3 / 4 = (4x4-3x5) / (4x5) = (16-15) / 20 = 1 / 20

5. Digital currency is sure to lose money, so we must be cautious

6. Of course, hi coin net will soon launch zcash. You can pay attention to Taihe's other currencies with large transaction volume.

8. It is not difficult to collect machine tool information. Two basic conditions are considered: first, whether the communication protocol of machine tool control system is open or not; Second, what data needs to be collected. No machine tool information can not be collected, of course, the premise must be that you know each other's communication protocol, no matter how you get it. Frank's system information collection should be very easy. For so many years in the instry, many companies are forced by the management cost and pressure to collect machine tool status, which is easy to achieve lean management. Mitsubishi, it seems that no one can get the communication protocol. As for the information collection of Mitsubishi machine tool, it is estimated that the protocol is not easy to obtain, unless you spend some effort

generally speaking, the operation data of machine tools need to be collected, such as shutdown, idle, processing, machine alarm information, etc; EDIT、MDI、MEM、HANDLE、FREE And part of the processing information, such as starting processing time, processing time, spindle feed rate, power load, current coordinates, etc. Generally do machine tool information collection is a certain management concept of the company will consider the implementation. At present, the companies providing such services are relatively large, and there are not many small and medium-sized companies. It's suggested to find companies with solid technology and good service. It doesn't mean that it's finished at once, but it needs follow-up maintenance. As far as I know, there are not many MDC companies in Suzhou.
