Amazing 99 ( Please Read)?

Question

Take any three diffrent digits,
eg 982,
flip it to get something like
289,
substract the smaller from the larger
982-289
Divide the results from the difference between the absolute value of the first digit and last digit ( in this case 2 and last 9)
What do you get?
Do for all combination.

The moral of the story, mathematics is easy and follows a certain pattern, and this pattern is what mathematicians try to find???
Thanks

Answer 1

An interesting observation, but trivially true.

XYZ - ZYX can be written as

100X + 10Y +Z - (100Z +10Y + X) =

100(X-Z) +Z-X = 100(X-Z) - (X-Z) = 99(X-Z) and hence your result of 99.

Simple arithmetic is easy. But try solving a problem like Fermat's last theorem. Ask Andrew Wiles if it was easy. Or solve the Riemann hypothesis and collect a cool million. From your 'pic' and words, you are obviously quite young. But you probably have some talent so enjoy exploring the world of math.

Answer 2

It's so Easy man...
let suppose we have 3 digits a,b,c
the Number is Z and its Flip is Y
then...
if we wirite Z = "abc" like "982", Y ="cba" like "289"
Z = 100a + 10b +c
Y = a + 10b +100c
So
Z-Y = 100a + 10b + c - a - 10b - 100c
Z-Y = 99a - 99c
Z-Y = 99 (a-c)
So
(Z-Y) / |a-c| = 99(a-c) / |a-c|
= 99
..........SO Easy Huh???

Answer 3

The first two posters are idiots.


If you actually thought this up, kudos to you. We need logical thinkers in the world.


Although I hate (Loathe, despise, pick a word) math, I give people who actually sit down and think this stuff up credit.


I couldn't do it.

Answer 4

well i got a headache now..thnx dude
