Where are the 6 bearings in the middle   

An interesting math problem

Hi everyone, here I come again! Linda from WXING Bearings. Last Sunday, my kids asked me an interesting math problem. Today I want to share it with you.

We can see this grid, each grid has a different number of bearings, but have you noticed that there is a common feature, the sum of the 4 grids on each side is 8. Let's check 1,2,3,4,5,6,7,8. There are 6 bearings in the middle grid. My kids asked me how to hide the middle bearing into the surrounding lattice, but keep the same number 8 for each side.

I practiced for a long time and finally figured out how to hide them, now let me show you all.

First, put this one on this side , then move this bearing to this grid. Let's count the bearings on this side. 1, 2, 3, 4, 5, 6, 7, 8. Wow, 8, great! 

Let's continue to put another bearing, which is also 8. Do you think it's amazing, haha.

Thank you for watching, I'm Linda, who sells bearings, from China.

I hope my videos bring a little lightness to your busy work. See you next time!
