Not sure it this is the appropriate area to post this, but I am having a really hard time figuring out modular arithmetic. Every time I think i have it I realize that I missed something. I need to know how modular arithmetic relates to time. I know that it is clock math, but I don't know how to find the right amount of numbers that should go around the clock. EX: 10mod(6), I know the answer is four, but that's only because I divided 10 by 6 and 4 is the remainder. I also don't know how to add (positive/negative) or multiply (positive/negative) in mod(7). I need someone to break this down for me like I'm a 2 yr old, because I'm obviously missing something. Please help. ANY relevant assistance in this matter would be greatly appreciated. Thank you in advance.
