Now I call this real Mental math. It can work on anything. WOW. Not just in tens, but just add zero to times 10, 20, 30 and so on. You just made me smarter today!!! 🧑🎓🧑🎓
I do it this way, I use 10 times 10 = 100, then I go 10 times 3 = 30, then I go 10 times 7 =70, then I go, 7 times 3 = 21. That's only if I can't remember neat math tricks lol

Hello sir
why didnt you use unit digit of 11 ?why you used 11+16 but not 1+6?
10 is the base here.. I'll create another video of calculating taking 20 as base number. That will clear the issue why we took 11 not 1 here..
