Modular Arithmatic and Cyphers
Modular arithmatic is like doing arithmatic on numbers on a clock, where the numbers wrap around at the edges.
Cryptography
Codes and cyphers often make use of modular arithmatic, as well as it being essential to many cryptographic algorithms
Clocks
Calculating the time on a clock, as well as working with days, weeks, months, and years uses modular arithmatic.
%
Remainders
