Yeah, you know you've been there.
Work has been a bitch to me this week and so I bring you a little nerdy math fun and an excuse you can always use when numbers don't go your way. It's not your fault!! It's because 2 = 1.
Here's the proof.
Suppose a = b.
Given that, a2 = ab
a2-b2 = ab - b2
using difference of squares we get
(a+b)(a-b) = b(a-b)
when we factor out a-b we get
a+b = b
or, b+b = b
or, 2 = 1.
See? Not your fault all those numbers don't add up!
Heh, as an aside, my partial differential equations prof refused to give me the results on my final exam until I found the error in this proof. Not gonna lie, it took me more than ten minutes. I was nervous, okay?

But ERROR: DIVBYZERO is something I sometimes get out of data analysis, so I've learnt to be sensitive to that as well. :)

Heh. Well, it probably wasn't actually ten minutes, but it was a good three or four reads of the proof before I spotted the mistake. I felt like such a tool!
In my defense, I hadn't seen an actual number in two years. You know what it's like to study math - every equation is nothing but variables. You forget they have actual values after a while :)
No though, it's nothing but numbers for me :(
