Factor | Numbers we can multiply together to get another number. Example: 2 and 3 are factors of 6, 2 × 3 = 6 |
Factor Pair | A pair of numbers that, when multiplied will result in a given product ( or the same product ). Example: (1 x 12)(2x6)(3x4) are the factor pairs of 12 |

Operations | addition, subtraction, multiplication, division |
Prime Number | A whole number greater than 1 whose only factors are 1 and itself. |

Square Number | is an integer that is the square of an integer; in other words, it is the product of some integer with itself. For example, 9 is a square number, since it can be written as 3 × 3. |
