# Math Terms To Stay

Term | Definition |
---|---|

Math | the systematic treatment of magnitude, relationships between figures and forms, and relations bet |

Multiplication | a mathematical operation, symbolized by a × b, a ⋅ b, a ∗ b, or ab, and signifying, when a and b are positive integers, that a is to be added to itself as many times as there are units |

Divison | The operation inverse to multiplication; the finding of a quantity, the quotient, that when multiplied by a given quantity, the divisor, gives another given quantity. |

associative property | property (which applies both to multiplication and addition) by which numbers can be added or multiplied in any order and still yield the same value, e.g. (a + b) + c = a + (b + c) or (ab)c = a(bc) |

coefficients | the factors of the terms (i.e. the numbers in front of the letters) in a mathematical expression or equation, e.g. in the expression 4x + 5y2 + 3z, the coefficients for x, y2 and z are 4, 5 and 3 respectively |

coordinate plane | a plane with two scaled perpendicular lines that intersect at the origin, usually designated x (horizontal axis) and y (vertical axis) |

distributive property | property whereby summing two numbers and then multiplying by another number yields the same value as multiplying both values by the other value and then adding them together, e.g. a(b + c) = ab + ac |

factor | a number that will divide into another number exactly, e.g. the factors of 10 are 1, 2 and 5 |

formula | a rule or equation describing the relationship of two or more variables or quantities, e.g. A = πr2 |

fraction | a way of writing rational numbers (numbers that are not whole numbers), also used to represent ratios or division, in the form of a numerator over a denominator, e.g. 3⁄5 (a unit fraction is a fraction whose numerator is 1) |

integers | whole numbers, both positive (natural numbers) and negative, including zero |

negative numbers | any integer, ration or real number which is less than 0, e.g. -743, -1.4, -√5 (but not √-1, which is an imaginary or complex number) |

number line | a line on which all points correspond to real numbers (a simple number line may only mark integers, but in theory all real numbers to +/- infinity can be shown on a number line) |

Dividend | the process of ascertaining how many times one number or quantity is contained in another. |
