one? There was 1 yuan money, but it fell by 3%. How much did it fall? ? The problem is highly concerned. Let me talk about my understanding. There was originally 1 yuan, down by 3%. How much money is left? The answer is that there is only 7 yuan left. How much does 5 yuan have to go up to become 1 yuan? The answer is a 1% increase. From here, we can see that there is a big gap between the decline of 1% and the increase of 1%. Here are the details. 1. How much is a 3% decline?

After a 3% decline, it is 7 yuan. This calculation method is very simple. We just multiply 1 by 7%, which is 7 yuan. This 7% is 3, and the rest is 7% after subtraction. 2. How much does it take to increase 5 yuan to become 1 yuan?

When 1 yuan falls to 5 yuan, the drop is 5%, but when 5 yuan rises to 1 yuan, it needs to be doubled, that is, it can only be achieved by increasing 1%. From here, we can see that it is more difficult to go up from below, and it is easier to go down from above. Third, the transaction must be prevented from retracement

That will be very enlightening for your stock or fund or futures trading, and we must prevent our money from losing. If you invest 1, yuan, you lose 5%, and then you want to earn 1, yuan back, then you need to earn 1% to earn back your principal. Losing money is twice as easy as making money. Every expert in trading, they are very good at controlling retracement, they attach great importance to risk and always put risk first to prevent their own retracement losses. If we can make a sustained and stable profit, then your money will be bigger soon, because the bigger our money, the faster we will actually earn. There is also a problem of compound interest here.

after reading it, remember to like it+pay attention to it+collect it.
