1 year agoMultiply 9 times any number and it always “reduces” back down to 9 (add up the individual numbers in the result)
For example: 9 x 872 = 7848, so you take 7848 and split it into 7 + 8 + 4 + 8 = 27, then do it again 2 + 7 = 9 and we’re back to 9
It can be a huge number and it still works:
9 x 987345734 = 8886111606
8+8+8+6+1+1+1+6+0+6 = 45
4+5 = 9
Also here’s a cool video about some more mind blowing math facts
don’t give a shit about MAGA but I’m all for MAHA with RFK Jr being on Trump’s team, keeping an eye on him to see if he’ll be able to take on the corrupt elements of Big Pharma and the FDA
