6 multiplication

  1. Sep 9, 2012 #1
    When I was little, I noticed that any even number less than 10 multiplied by 6 ends in itself and leads with one half of itself.

    Any meaning behind that, or coincidence?

    I decided to write it like this:

    Since it leads with half of itself and ends with itself, I made that a sum by saying it is ten times half itself plus itself.

    Or in other words,

    6n = (10)(.5)n + n
    6n = 5n + n

    Oh math, you.
