Cursed Math - Blog Posts

I hope this makes it more obvious that you can get any number from a diverging sequence if you rearrange it enough.

wanna see some cursed math?

people are always saying that 1+2+3+4+5+6+7+... is equal to -1/12. that's stupid. why would adding positive numbers add up to a negative? so i decided to take matters in my own hands.

The sum of all natural numbers is 1.

(added some random stuff to make it even harder to understand)

explanation of last step

the sum (as n starts from 1 and approaches infinity) of 3n-1

= 2+5+8+11+14+17+20+... = infinity

the sum (as n starts from 1 and approaches infinity) of 2n

= 2+4+6+8+10+12+14+... = infinity

these sums are the same. so we divide both sides by

∞

Σ

n=1

to get 3n-1= 2n, so n=1
