Question

need help about this sign %
7%3=1 i can understand this,
but 3%7=3 i can't understand it at all
explane please

Answer 1

% gives the remainder of division in either case.
For 7 % 3, 3 goes into 7 twice, with remainder 1.
For 3 % 7, 7 goes into 3 zero times, with remainder 3.

Answer 2

7%3 = 1 (% gives the remainder)
3%7 = 3 (as 3 is the remainder)
