Does this have any meaning:
x = (-6) mod 5
Is it just like:
x = -(6 mod 5)
Or what about:
x = 6 mod (-5)
And:
x = 6 mod (5/2)
x = (-6) mod 5
Is it just like:
x = -(6 mod 5)
Or what about:
x = 6 mod (-5)
And:
x = 6 mod (5/2)

Chen said:Alright, thanks. I was just wondering really how far you can take this action.
One more thing, how can I prove that xmk mod k = 1 for every x, m and k? I hope it's not too complicated.
The expression "x = (-6) mod 5" means that x equals the remainder when -6 is divided by 5. In other words, it is the number that is left over after dividing -6 by 5.
The two expressions are not equivalent. "x = -(6" is not a complete mathematical expression and does not have a clear meaning. On the other hand, "x = (-6) mod 5" is a valid mathematical expression with a specific meaning.
Yes, x can be a negative number in this expression. The result of a mod operation can be positive or negative, depending on the sign of the dividend (in this case, -6).
The "mod" (short for modulo) operation is used to find the remainder after dividing two numbers. It is commonly used in various mathematical concepts, such as number theory, algebra, and cryptography.
To calculate "x = (-6) mod 5", you can use the following steps:
