Key Concepts

A system dealing with remainders when

A system dealing with remainders when integers are divided. X mod Y = R means X leaves remainder R when divided by Y. Properties include (A+B) mod C =

Two integers a and b

Two integers a and b are congruent modulo m (written as a ≡ b (mod m)) if (a-b) is divisible by m, or equivalently if a mod m = b mod m. This creates

Functions from positive integers to real/complex

Functions from positive integers to real/complex numbers. Key examples: Euler's totient function φ(n) counts numbers ≤ n coprime to n; divisor functio

Mathematical technique to find ratios

Mathematical technique to find ratios for mixing ingredients of different costs to achieve a desired average cost. The rule states that quantities are

Problems involving relative motion where boat

Problems involving relative motion where boat speed in still water and stream speed affect downstream (with current) and upstream (against current) sp
