Exponential Notation | A shorthand way of representing repeated multiplication of the same factor. |

Scientific Notation | Where a number is written in two parts:First: just the digits (with the decimal point placed after the first digit),Followed by: ×10 to a power that would put the decimal point back where it should be. |

Prime Factorization | A number, expressed as a product of prime factors. For example, of 24 is 2 x 2 x 2 x 3. |

Decimal | A fraction that has a denominator of a power of ten, the power depending on or deciding the decimal place. |

Whole Numbers | The numbers {0, 1, 2, 3,…} There is no fractional or decimal part and no negatives. |
