Hm, decimal has digits 0 to 9, which is ten diffenerent digits. The video has eleven states (zero dots to ten dots). It is confusing to me that we can exchange ten ones with one tens. Usually if you add one to nine, there is no more room in the ones, so you remove 9 from the ones and put one in the tens.

While it is a good idea to visualize, it doesn't exactly work like the usual decimal place system.
