Brush the math problem of Dawt's comma, 6 3=39, 8 5=313, 5 1=46, ask 9 2 is equal to number. I stared at this pile of numbers for a long time, and almost pressed the calculator to smoke - how can normal addition calculate like this?

At first, I thought it was to find the law of numbers, such as 6 3 = 9, but 39 and 9 can't be matched.

I suddenly remembered the secret game I played when I was a child, maybe it was a combination of two numbers of difference and sum? I tried 6-3=3,6 3=9,Spell it up exactly 39! Hey, that's it!

Then the test proves 8-5=3, 8 5=13, spells up 313, and didn't run. 5-1=4,5 1=6,46 also matches. 9-2 = 7, 9 2 = 11, isn't the answer 711?

A colleague next to him glanced at it, not saying that this was an "anti-human calculation", but after calculating it, he smiled like a child. This topic is like a matter in life, such as stripping an orange, some people from the tail, some people from the top, looking different, and finally eating meat.

In fact, this kind of question is like giving a brain a pinch, and the answer is hidden in the most conspicuous place, and it takes a few circles to find out. If you also encounter it, don't rush to add or subtract, maybe change the angle, and the answer will pop up immediately. Do you dare to try? The moment you figure out 711, make sure you want to slap your thigh – that's so simple!
