Show that the sum of 2n + 1 consecutive integers is divisible by 2n + 1. Let a be the starting number. Then the 2n+1 consecutive numbers are a,a+1,a+2,\ldots,a+2n The sum of these number is S (a,n) = (2n+1)a + \dfrac {2n (2n+1)}2 = (2n+1) (a+n) Clearly, (2n+1) \mid S (a,n) ...

So, I made this video to share a very simple proof....more. I think we've all had the question (at least once) on why 1+1=2. It's like asking the definition of 'the', and it's rather...

Some idea of the scope and comprehensiveness of the “Principia” can be gleaned from the fact that it takes over 360 pages to prove definitively that 1 + 1 = 2. Today, it is widely considered …
