I solved the examples in the video just in my head
Yep, easy using what they call "new math", even though I've never known another way.
15x20= (15x2) = 30 + ending 0 = 300
15x2 = 30
300+30 = 330
, all done in your head, faster than you could type it into a calculator.
Still, the video method is kind of neat though...but personally, I like the above method.
It's both funny and sad when I tend to freak people out doing this. I don't see it as being difficult, in fact, just the opposite, makes it easy, but
