Recently, a math problem on the Internet suddenly became popular, and many people are discussing it. The title goes like this:

9=72, 8=56, 7=42, 6=30, 5=20, so what is 3?
There are four options: A.6 B.9 C.12 D.30

At first glance, do you think it's simple? But after thinking about it carefully, I found that there were many mysteries hidden in it, and different answers could actually reflect different personalities! Let's have a good chat

First of all, let's talk about the law of the question, how do you calculate it?

Some people will see that the law is obvious: 9 times 8 gives 72, 8 times 7 gets 56, 7 times 6 gets 42, 6 times 5 gets 30, 5 times 4 gets 20, then 3 should be multiplied by 2, 6, and choose A

This is a typical logical algorithm, step-by-step, especially strict

But some people feel that it is wrong: the front is all n times (n-1), but when it comes to 3, there is no 2 behind, what should I do? It should be looked the other way around, 3 times 4 to get 12, choose C

This kind of thinking is a bit out of the box, not according to the convention, pay attention to flexibility

There are also people who choose B intuitively, and feel that 3 and 9 seem to be related, so they choose 9 directly
