1234567890:90=13717421
9876543210:90=10973969
10973969+13717421=123456790
Tadah, the 8 is gone.
Extra note: The root of 123456790=11111.11111
And the really cool part is, it doesnt just work with 1234567890 and 9876543210.
You can tap any sequence of numbers, turn around the calculator and tap the same sequence, devide both numbers by 90 and add them together to get the same numer.
For example:
5732416890:90=63693521
5378694210:90= 59763269
59763269+63693521=123456790
I was bored a lot during math and just played with my calculator and one time I found this out.
Fun nerdy video (not knocking nerds!) on the subject.
