I usually do some funny calculations when i am bored. So, i recently heard an information that people in our country wont usually purchase the register number for vehicles which adds up to 8 . For example
An example number:
TN 56 FZ 2267.
Add numbers in 2267 => 2+2+6+7=17 . Add numbers in 17 => 1+7 =8. Let us call this operation as Add() functions as like in C programming. ( For future use)
Like that.
So by this i came to figure out something. An interesting fact. Don't know whether you might know this already but I am bound to tell it because it is interesting.
Suppose i give you a number 3699. Add numbers in 3699
3+6+9+9 = 27. Add numbers in 27 you get 2+7=9. So simple as it is , but do u see something very common?
When ever we perform Add() function , which involves a number '9' in it, we can perform it quickly with less effort.
I call Add() function for Number 69. the result is 6. Note the other number than 9. It is 6. so the result is same as the other number than 9. So whenever u find series of number before 9 or a string of number which contains 9, u add up the rest other than 9 and that will be the result when you perform Add() function. So the concept is pretty simple. YET ANOTHER CONCEPT.
I've also found something in common in multiples of five. what is 8x5? its 40. What is 6x5? its is 30. So what do you infer?.. 8x5=40 . 4 is half of 8 and 10 is multiplied with it. 6x5=30 where 3 is half of 6 and 10 is multiplied with it. So you can perform multiplication using five table easily than ever.
what is 124567345 x 5? = 622836725.
If you also know some funky concepts please feel free to post it.
