On this day, it was raining cats and dogs outside the window, and the distant scenery was hazy. Raindrops beat on the earth, causing ripples in circles. I sat by the window and thought of a math problem: country A and country B have their own currencies, and the currency exchange between the two countries is very interesting. In country A, 2 yuan money in country A is equal to 3 yuan money in country B; In country B, 2 yuan in country B is equal to 3 yuan in country A, and there is no limit on the amount of each exchange, but a handling fee of 16 yuan is required after each exchange (any national currency is acceptable). A clever doctor, now in country A, only has the currency of country A 160 yuan. He wants to go back and forth between country A and country B, and increase his money to 1000 yuan by changing money. Now, my IQ has been very good, and it's no use thinking hard. It's still raining. I checked my books and turned over my notes, but I couldn't find any hints.
I rubbed my temples and frowned. Suddenly, I had a brainwave: "That's right! If you can't use arithmetic, use the whole line of the equation! " However, which one is unknown? I can't help but get lost in thought again. What is the currency of country A? I can't ... by the way, suppose I have to cross the border at least x times. I calculated it excitedly. Unexpectedly, this problem is too difficult to solve the equation. I bit my head for a while and propped my head up for a while. Just when I was puzzled, I suddenly remembered what my teacher had taught me. Thinking of a new solution, I couldn't help laughing and trying to come up with it. In the end, everything paid off. Outside the window, the rain stopped, and Sun Dad's smiling face appeared again.
I finally overcame the difficulties and realized that the biggest difference between winners and losers lies in their attitude towards difficulties and whether they can overcome them. When difficulties come, winners are confident and optimistic, go forward bravely and step on their feet. Losers complain about others, feel depressed, are blocked by difficulties, and cannot reach the other side of success.
