Amazing 9! « Foor for Thoughts

June 5, 2008

A friend of mine forwarded this SMS:

When multiplied by any number, nine returns to nine.

9 x 1 = 9 ( 9 + 0 = 9 )

9 x 2 = 18 ( 1 + 8 = 9 )

9 x 3 = 27 ( 2 + 7 = 9 )

9 x 4 = 36 ( 3 + 6 = 9 )

9 x 5 = 45 ( 4 + 5 = 9 )

9 x 6 = 54 ( 5 + 4 = 9 )

9 x 7 = 63 ( 6 + 3 = 9)

9 x 8 = 72 ( 7 + 2 = 9)

9×9 = 81 ( 8 + 1 = 9)

Like the number 9, whatever life may brings us, we will always return to our source back to God.

awts… in mathematics, there is a technique so that we can determine whether a number is divisible by a certain number:

we can tell if a number is divisible by 3 when the sum of its digits is exactly divisible by 3.. example:

36129
3 + 6 + 1 + 2 + 9 = 21
2 + 1 = 3

The final sum is 3 which is exactly divisible by 3..

we can tell if a number is divisible by 4 when the last 2 digits is exactly divisible by 4.. example:

3245633580
Last 2 digits is 80, so this number is exactly divisible by 4 since 80 / 4 = 20.

we can tell if a number is divisible by 5 when the last digit is either 5 or 0.

we can tell if a number is divisible by 6 when the sum of the digits is exactly divisible by 3 and is an even number..

we can tell if a number is divisible by 9 when the final sum of its digits is 9.. example:

81276354
8 + 1 + 2 + 7 + 6 + 3 + 5 + 4 = 36
3 + 6 = 9

Ehehe.. i dunno sa 7 and 8… ehehe.. gamit nlng ug calculator :p
