I just brushed up on a super interesting multiplication problem that almost made me doubt my math ability! The question is 11×11=4,22×22=16, ask what 33×33 is equal to, and say that ten people answered nine wrong, and the curiosity was instantly aroused.

At first, I calculated according to the common multiplication, 11×11 is obviously 121, how can it be equal to 4? This is obviously not an ordinary multiplication problem, you have to find special rules.

I stared at the numbers for a long time, and suddenly found that - look at the number of the same number in the number! 11 is two 1s, 2×2=4, just good correspondence; 22 is two 2s, 4×4=16, also perfectly matched!

Those 33 are two 3s, according to the law, 6×6=36! It turned out that this problem was a routine of playing "number splitting multiplication," and it was almost stuck in the thinking of regular multiplication.

When I think of similar problems I have encountered in the past, I have relied on breaking the rules of the norm, just like the "brain teasers" encountered in life, and if I think about the problem from a different angle, the answer will be clear.

Were you also frightened at first? This kind of "anti-routine" question is especially suitable for testing friends, to see who can break this "number trap" in seconds, and will definitely be able to receive a bunch of "miserable" complaints, which is lively and interesting, hurry up and try~
