Recently, I brushed up on an Olympiad math problem, which instantly aroused my desire to win.

At first glance, it was a little confusing, but on second thought, the AA here should be two digits, the ten digits and the individual digits are both A, which is actually (10×A A)

In this way, the formula becomes (A 10A A) = 72, that is, 12A = 72, then A is not 6!

This kind of numerical reasoning is like those "bluffing" things encountered in life, such as complex home phone instructions, which at first glance look big and are broken down into small steps. This topic is also the same, and the translation of AA into mathematical language is immediately clear.

When I think of my childhood, I was always overwhelmed by strange expressions, but now I understand that many times I don't find a way to "translate". It's like communicating with people, changing the way to explain the words, and it's done.

So, when you encounter a difficult problem, don't panic, dismantle it, the "difficult problem" in life is the same, disassemble it into small goals, step by step, the answer will naturally come out, do you say this is the reason~
