Pointing at the question, Chi An asked the little boy, "One jug of oil costs 54 yuan. How much do two cost?"
"Um... 108."
"Okay, the supermarket has a buy-two-get-one-free promotion. You spend 108 on two jugs of oil. How many jugs do you get altogether?"

[Sometimes I genuinely lose all hope. I have no idea how these kids' brains are wired.]
[Every time I help my little brother with his homework, I want to open his head and check whether it's empty inside.]

"...Lollipops cost one yuan each. Today is the shop owner's birthday, so it's buy one, get one free. How many can you get for one yuan?" Rephrasing the question, Chi An looked at him and asked again.

"Because it's the owner's birthday and he's happy, I can take two. But oil is expensive. One jug costs 54. If I buy two for 108 and take another one, the owner will get angry." Convinced that his reasoning made perfect sense, the
