Oh no… imstkaes!

Sorry, but you do know that I am a human, and therefore makes misatkes. But they do help us learn, and I has learned from mi miskates. Here we go!

  • In the Happy 3.141592653589793238462643385279… Day! post, I got the digits in the title wrong. The bold numbers say that it’s 5279 in the last few digits that I wrote, but it’s actually 3279.
  • In the Zero Is? I say “Wait. Who said it was PRIME?” but I actually meant “Wait. Who said it WASN’T prime?” Sorry!
  • The Tangram is not a toy. Sorry, 5-year-old kiddies!
  • In the blog about feeding people 0 pizzas, I stated that

So 5/0 = um, 0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0 = STILL ZERO!!!!! SO 5 could not be reached.


then 5/1 = 1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1= um, 42. So no, the text above (So 5/0 = um,) is incorrect.

  • I stated in Maths, but simpler that Topology: stretching, bending and squeezing solids to make them into different things, but 2D shapes are allowed.

I cna’t go on aymorne. I wlil sotp and fsniih tihs bolg.


Zero is?

Zero, right?

But it’s complicated again! Is it prime or composite?

I was having a look-around on Math Stack Exchange Is zero a prime number? and it was absolutely confusing. Give it a read!

It’s not prime, so it should b —

(Screech sound)

Wait. Who said it was PRIME? Not me. Let’s prove it!

If zero was prime, then it has no divisors. Let’s see, it has divisors of 0, 1, 2 (2*0=0), 3, 4, 5, 6, 7, 8, 9, 10, blah blah blah, so it’s not prime!

So it’s … composite?

Maybe? I mean we just proved it’s not prime, so it should be composite, right?

There’s a program on Khan Academy called Level 10: Fermat Primality Test and it says composite!


P.S. Comment below on what you think 0 is.

Some great math webs/books



Oh wait, youtube channels!!!!!

That’s all folks. But if you have any favorite math web, book or YouTube channel, comment below.

Right, bye guys!
