What is modular arithmetic? (article) | Khan Academy
Many programming languages, and calculators, have a mod operator, typically represented with the % symbol. If you calculate the result of a negative number, some languages will give you a negative result.
Congruence modulo (article) | Cryptography | Khan Academy
A primitive root, g, that when repeatedly multiplied by itself (mod n) generates all the numbers coprime to n. It is also called a generator (mod n). If n is prime it will generate all the numbers between 1 and …

Modular multiplication (article) | Khan Academy
Let's explore the multiplication property of modular arithmetic: (A * B) mod C = (A mod C * B mod C) mod C
Statistics intro: Mean, median, & mode (video) | Khan Academy
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to …

Mean, median, and mode review (article) | Khan Academy
Finding the mode The mode is the most commonly occurring data point in a dataset. The mode is useful when there are a lot of repeated values in a dataset. There can be no mode, one mode, or multiple …
Modular addition and subtraction (article) | Khan Academy
We ignore these complete loops around the circle by calculating each number mod 7 (as shown in the two upper modular circles). This will give us the number of clockwise steps, relative to 0, that …
Fermat's little theorem (video) | Khan Academy
"a mod p" is the remainder we get when we divide "a" by "p" If "a<p" then "a mod p = a", which means "a^p mod p = a", which means "a^p" divide by "p" will give you a remainder of "a".
