Math Things About Missing 8 But Not Number 9.
A long time ago when I used my Casio Calculator in school, someone showed me something strange!
Actually any calculator or app will do.
The instructions were simple, to type in digits 1 to 9 and skip number 8.
Once I did that, I needed to press the Multiplication Symbol.
The next step was for me to say what SINGLE DIGIT number I wanted to see 9 times on the screen!
I said number 7 in which case I needed to type into the calculator, number 63, then press the Equal Sign.
Sure enough, I noticed number 7 seen NINE TIMES on my display: 777777777
I WAS AMAZED. And Confused. I know it's not a trick, but some type of math thing.
Once I got home, I tried it again KNOWINGLY which 'calculator number' to use.
I picked number 3, to see it my calculator would show it nine times.
My calculator did indeed show: 333333333
Math Thing = Use a single digit number and multiply it by NINE to get the 'calculator number' to use.
To clarify, if you want to see a bunch of 3's, then 3 x 9 = 27, hence 12345679 x 27 = 333333333
Addendum:
If you try to use two digits instead of a single digit, answers are more complex.
For example, lets try the Letter Q (aka 17).
Well them 17 x 9 = 153
Calculator time: 12345679 x 153 = 1888888887
The above shows EIGHT 8's between number 17, ten digits in total.
When you add up the single digits of 1888888887 you get number 72, for which Q Post 72 is attached.
And since so much stretchy math is involved, lets add up digits 72 to attach Q Post 9, because 7 + 2 = NINE.
The not obvious thing is that the first number 1 and last number 7 has the sum of 8, notwithstanding the 8 digits of number 8 within them.
