ENJOY THE BEAUTY OF NUMBERS !!!
This app consists of two modes :
1. Multiple Mode :
Given any number n, excluding multiples of 2 or 5, we can find a multiple of n which entirely consists of 1's only.
For example given 3 (neither divisible by 2 nor 5) as input, the output 111 is divisible by 3 (i.e. 111 is a multiple of 3)
and given 7 (neither divisible by 2 nor 5) as input, the output 111111 is divisible by 7.
43 is input and the output is given below :
-------------------------------------------
111111111111111111111 (21 digits number) which is divisible by 43.
4967 is input and the output is given below :
---------------------------------------------
1111111...111111 (4966 digits number) which is divisible by 4967.
4943 is input and the output is given below :
---------------------------------------------
1111111...111111 (4942 digits number) which is divisible by 4943.
6801 is input and the output is given below :
---------------------------------------------
1111111...111111 (3399 digits number) which is divisible by 6801.
*** WARNING :
For some numbers, mobile devices may hang as it might take huge time for computation.
In this mode n can be entered as input and the app will give the proper multiple of n satisfying the above mentioned condition.
App will take input between 2 to 10000.
*** WARNING :
For some numbers, it may return no result.
2. Sum Mode :
Any integer number n can be expressed as
n = (+/-)1^2(+/-)2^2(+/-)3^2(+/-) .... (+/-)N^2
Here (+/-) means either + or - and N is an integer.
For example :
2 = -(1^2+2^2+3^2)+4^2
5 = 1^2+2^2
79 = +1^2+2^2+3^2-4^2-5^2+6^2-7^2 + 8^2 - 9^2+10^2 - 11^2 +12^2 +13^2 + 14^2 - 15^2-16^2+17^2-18^2-19^2-20^2+21^2+22^2
90 = -(-(-(-(-(-(-(-(-(+1^2+2^2)+3^2)+4^2)+5^2+6^2+7^2)+8^2)+9^2+10^2)+11^2+12^2)+13^2+14^2)+15^2)
In this mode n can be entered as input and the app will give the required expression for n.
App will take input between 1 to 100.
Play with this app to have ideas about some of the peculiar properties of numbers.
This app is ABSOLUTELY FREE, contains NO-ADS or IN-APP PURCHASES.
