REAL or FAKE : Kids Quickly Executing Math Problems in their Heads

Most of those are fake and offer minimal results at best

and the part when the kid instantly solved the square root problem, it is completely fake,

Even the person on the documentary called "brain man" who is is able to do mental math pretty much better than any other human and better than most calculators, it took him a while to solve square root Problems and also long multiplication problems.

Most of these people often get fined for false advertising but due to very light punishments, they still make a profit.

A while back there use to be TV ads for a speed reading program that claimed to increase reading by some large percentage, and the video showed children (most likely pretending) to read a full page of text, probably 300-400 words in about 2-3 seconds

The company was fined and they walked away with a lot of money left over.

Most of these programs are often based on repetition, after you do a certain math problem a lot, you get faster at it and depending on the complexity of the calculation, some of the calculation can be done in your head.

PS some complex equations are solved with many steps which require basic math, those can be done mentally if you train your self enough.

Little-known fact about me: I can do that. :) I'm by far not a genius. However, I was always the 'math whiz' in school. From a very young age, I could do all of my math in my head. I never needed a calculator, pencil or paper. I was accused of cheating on more than one occasion until teachers got to know me.

I have no idea how I do it. My Dad is the same way. The funny thing is that I ended up going to college to be an Accountant. I figured I "should" do so. I also DO enjoy math and numbers, figuring things out, etc. However, after several years in the "rat race," I realized how much I hated it.

I still do all types of math in my head as needed, but I spend my time hanging out with all of you as a job instead of sitting in some stuffy office.

Seems like a pretty excellent trade-off to me. ;)

I believe it can be real. I have a friend who can do advanced algebra, square roots, fractions, exponents, surface areas, volumes, etc...all in his head in a matter of seconds.

It can be real. When I was a kid I did all sorts of calculations in my head. My teachers wanted me to show my work, but when I did they accused me of skipping steps. The problem was that I didn't even follow the steps I wrote half of the time. Quite often I just knew the answer. It wasn't until later on that I learned why.
