For students like us who wander in the ocean of knowledge, the biggest difficulty is those puzzling problems. I always rack my brains to overcome them.
On this day, it was raining cats and dogs outside the window, and the distant scenery was hazy. Raindrops beat the earth and ripple again and again. I sat at the window, thinking about a math problem. It gives us a rectangle, divided into four triangles with different sizes, and only tells us the area of one triangle! Now, my IQ is not too bad, and I haven't come up with an idea after thinking hard. It's still raining, banging on the ground. I looked up the book and turned over my notes, but I couldn't find any tips to solve the problem.
I rubbed my temples and frowned, trying to recall the topics I had done before, hoping to get some clues. Suddenly, I had a brainwave: "That's right! I can't use arithmetic, just use equations! " However, which unknown is set? I can't help but get lost in thought again. Set a rectangular area? No Set triangle area? Neither can i. Suppose ... I thought about it for a long time, and suddenly my eyes lit up, right! Set the length to x! Following this train of thought, I quickly found out the equivalence relation and calculated it excitedly. I didn't expect this problem to be so difficult that a series of equations could not be solved. I bit my pen, propped my head and held my finger, and I couldn't think of anything.
Just when I was puzzled, I suddenly remembered the equation that the teacher had told me before. Thinking of this solution, I couldn't help beaming, clapping my hands excitedly, and burying my head in careful calculation. However, just when I was about to successfully apply various laws, a new problem appeared-the symbols before and after the equal sign were different! I sighed and lost in thought again. At this point, the heavy rain outside the window gradually decreased, without the previous fury.
I think silently, but I still have no clue. Suddenly, my father's previous words were ringing in my ears again-"The left and right sides of the equation can be expanded several times at the same time, and addition and subtraction can offset them." I was suddenly enlightened and all the problems were solved. After a while, a number "4" appeared in front of me. "Don't be too happy!" I reminded myself to check it again. Wow, 1 it's okay! I couldn't restrain my inner joy any longer, and cried happily, "Yeah!" I want to come out! Hooray! "Out of the window, the rain stopped, and Sun's father's smiling face appeared again.
I finally succeeded, and I understand a truth: as long as I go all out and make unremitting efforts, I will definitely overcome difficulties and taste the joy of success!
