Let n belongs to N and given a belongs to Z, let a* represent the congruence class of a modulo n. if a1* = a2* and b1* = b2* for integers a1,a2,b1,b2, then prove that (a1b1)* = (a2b2)*.

if p is a prime, explain why all elements in Z / pZ have multiplicative inverses.

if a, b & c are positive real constants. Find the positive real solutions x, y & z in terms of a, b, & c in the equations:

x + y + z = a + b + c
4xyz - (a²x + b²y + c²z) = abc

I have an input byte stream consisting of numbers in the set {0 - 15} exclusively of about 1000 bytes.

What I would like to do is to be able to somehow store that mathematically in ONE unsigned integer and then, having in hand the the last byte value that was "encoded" into that unsigned integer, mathematically reverse it back to the original byte stream.

I am hoping there is a way to mathematically encode the values into an integer and then decoding them back.

Do you know how?
