Exponential form - When a number is multiplied by itself multiple times, it can be written more simply in exponential form.
Commutative - An operation is commutative if the values it is operating on can be written in either order without changing the calculation.
Prime number - A prime number is an integer greater than one with exactly 2 factors. All integers greater than 1 are either composite or prime.
Prime factor - Prime factors are the factors of a number that are, themselves, prime.
Prime factorisation - Prime factorisation is a method to find the prime factors of a given integer.
Use of addition instead of multiplication when finding factors.
Reiterate that the product of prime factors is unique.
