It seems like earning 2 bucks, but there should be a trap. Hmm, let me think about it!

Forget it, I'll go with E! Is there a prize for answering correctly?

Egg Ding was wrong, actually the answer is b. We just need to use the solution method we've used countless times for arithmetic problems! Answer: -9 + 10 - 11 + 12 = 2. Even elementary school students can calculate it, of course, we once could too!

So it's two pieces after all! I'm dizzy! Wait a moment, let me think of a question too.

This kind of problem involving buying and selling needs to be calculated step by step.

First of all, this person bought a chicken for 9 yuan. His initial cost was 9 yuan, and then he sold it for 10 yuan, so he made a profit of 1 yuan. Then, he took this pitiful 10 yuan in his hand and bought a chicken for 11 yuan. At this point, did he lose 1 yuan? The cost of this chicken was 11 yuan, and he sold it for 12 yuan, so he made another 1 yuan. So far, in total, he made 1 yuan, lost 1 yuan, and made 1 yuan again: 1 - 1 + 1 = 1 yuan. After all this fuss, he only made 1 yuan. But little did he know, the original 9-yuan chicken could have been sold for 12 yuan, netting a profit of 3 yuan, and after all this trouble, he only made 1 yuan. Overall, he actually lost 2 yuan.

The main gate, I admire you, truly worthy of being a high-IQ person. I'll leave the future math homework to you. Haha.

No problem. Ah, in the future, you won't come to me for math problems, right? Anything below 3rd grade is fine, you can ask freely.

Don't be so polite. We're just like that with each other.

Hehe, why should I be polite? You're way too modest!
