The Only Numbers You Need To Do Math - Business Insider

Great, another math related article from Business Insider. See http://www.businessinsider.com/numbers-you-need-to-do-math-2014-9?op=1.

8 special numbers to do math? Ooh what are they?

Oh they are: 0, 1, -1, 1/10, sqrt(2), π, e, i

The author simply introduce the number sets... why doesn't the author bring out a Venn diagram or the Russian dolls? He even got the natural numbers wrong. Look, the natural numbers are 1,2,3,... counting the natural way. Have you seen a baby start counting with 0? 0,1,2,3,... are non-negative whole numbers.

Natural numbers, then add 0 to it, the negative numbers, fractions, irrational, transcendental, imaginary.

That's high school student knowledge rehashed as some business article?

And the author didn't bother to show the glamorous Euler identity linking 5 of the numbers above? I am a bit disappointed.
