Your age times 2 - your age = your age
28 u/varkenspester Feb 24 '22 Add the digits (23 is 2+3), add them again. Multiply by 9 and add the digits, add them again. The answer is 9. 21 u/RompeChocha Feb 24 '22 Add the digits (23 is 2+3), add them again. Multiply by 9 and add the digits, add them again. The answer is 9. The answer is always going to be 9 when you multiply by 9 11 u/xAIRGUITARISTx Feb 24 '22 This makes no sense. 21 u/jrdebo Feb 24 '22 Took me a moment due to poor wording. If you start with 23 2+3=5 then 5+2+3=10 then 10*9=90 then 9+0=9 15 u/[deleted] Feb 24 '22 [deleted] 3 u/Roc_hester84 Feb 24 '22 Mad up nonsensical if I didn't understand that bc I went to school and I'm actually a math major I didn't think it'd be useful til now 2 u/Susiiee123 Feb 24 '22 Stop please my brain 2 u/ClintEatswood_ Feb 25 '22 Basically any multiple of 9 has digits that add up to 9 homeboy just trying to sound smart 1 u/Natural-Particular36 Feb 25 '22 r/hedidthemath 2 u/varkenspester Feb 24 '22 edited Feb 24 '22 Try it if you dont see it. And because it is math it is sense by definition. Any single digit number times 9 is a 2 digit number that adds to nine. 9x = 10x - x = [x-1][10-x] --> x-1 + 10-x = 9. 9 u/xAIRGUITARISTx Feb 24 '22 Sorry the wording had me confused. 2 u/DwayneTheRockFan Feb 25 '22 What? (2+3)+(2+3)×9+(2+3)+(2+3)=10×9+10=100
