A prime number is a
positive integer greater than or equal to 2 divisible only by 1 and itself, to be
more precise
This means that the positive integer 1, by definition, is not a prime number. The reason I
mentioned this is that they used to consider 1 a prime number (which is precisely why they restated this
mathematical postulate called “Goldbach’s Conjecture” to a more modernized version, if you will).
However, in the 1800s, mathematicians decided to change the formal definition of a prime number so that 1 is no
longer considered a prime; this makes sense to me, since the fundamental theorem of arithmetic, which states that
all natural numbers greater than 1 have a unique prime factorization, would also make sense (e.g., if 1 were a
prime number, then 4 wouldn’t have a unique prime factorization because it can be written as 2 x 2 or 2 x 2 x 1,
etc.) In short, it’s actually been a while since they last changed the definition of a prime number…

Anyway, back on topic… I’ve seen one episode of [i]Are You Smarter than a Fifth
Grader?[/i] and I actually really liked the show (I’m from Canada, so there were a few U.S. History
questions that I either had to guess on or just flat out got wrong
) I’m hoping to see more of it once I
finish my finals.
