Face setbacks

For our students who roam in the sea of knowledge, the most difficult problem is that one by one, I always struggle to overcome them.On this day, it‘s raining cats and dogs outside the window.

The scenery in the distance is hazy. The raindrops knock on the earth and make ripples one after another. I was sitting in front of the window, thinking about a math problem. It gave us a rectangle, divided it into four triangles of different sizes, but only told us the area of one of them! This time, I’m not too poor in IQ, and I‘ve also made difficulties, and I haven’t come up with a reason to think about it. The rain is still beating on the ground. I look up books and turn over notes, but I can‘t find any tips to solve the problem.I rubbed my temples, frowned tightly, and tried to recall the questions I had done before, hoping for some clues. All of a sudden, I had an idea: “right! I can’t use arithmetic, just use the total line of the equation! ”

But which unknown number should be set? I couldn‘t help thinking again. What is the area of the rectangle? no way. Set triangle area? Not either. Set After thinking for a long time, my eyes suddenly brightened, right! Set length to X! Following this line of thought, I quickly found out the equivalent relationship and calculated it excitedly. Unexpectedly, this problem is so difficult that a series of equations can not be solved. I bite the pen, hold my head, and hold my fingers. I can’t think of it.Just when I couldn‘t think of the solution, I suddenly thought of the equation that my teacher had said before. Thinking of this solution, I couldn’t help but smile, clap my hands excitedly, and count carefully. However, when I am about to succeed in applying various laws, a new problem arises: the symbols before and after the equal sign are different! I sighed and lost myself in thought again. At this time, the heavy rain outside the window gradually small, without the previous violent.I think silently, but I still have no clue.

All of a sudden, Dad‘s words lingered in his ears: “the left and right sides of the equation can be expanded several times at the same time, and the addition and subtraction can be offset.” All of a sudden, all the problems were solved. In a moment, a number “4” appeared in front of me. “Don’t be too early!” I remind myself to check again. Wow, it‘s all right! I can’t hold back the joy in my heart any more, and I cried happily, “Yeah! I want to come out! Long live! ”

Outside the window, the rain stopped, and the smiling face of father-in-law sun reappeared.I finally overcome the difficulties and understand a truth: as long as I try my best and make unremitting efforts, I will be able to overcome the difficulties and taste the joy of success!
