Hi! Some of you might find it amusing, but I'll do it anyway. So, I need to get x if x = 15 (mod 25); I've never understood the concept of this. In some places I find that x=15, others say it's x=10 and again others that x=6. What now?
How can you have 15mod25? Do you mean 25mod15? Then the answer is 10. Ill be honest and say until I read your post id never even heard of mod! Silly considering ive got a uni qualification in maths! I might be barking up the wrong tree altogether with my reply but a quick google hows mod is really simple.
ok, if we consider 15 (mod 25) and I need to get my number, then google gives me three answers - 15 mod 25 = 15; 25 mod 15 = 10; 15 mod 25 = ~0,6 (the remainder of dividing these numbers). jeez... which freakin' is the damn correct one?
