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

Equation | an expression or a proposition, often algebraic, asserting the equality of two quantities. |

Expression | Numbers, symbols and operators (such as + and ×) grouped together that show the value of something. |

Algorithm | An Algorithm is a step-by-step solution to a problem. It is like a cooking recipe for mathematics. Example: one Algorithm for adding two digit numbers is "add the units, add the tens and combine |

Coefficient | A number used to multiply a variable |

Simplify | Simplify the fraction (if needed) |

Evaluate | to ascertain the numerical value of (a function, relation, etc.). |

Like Term | Like Terms more ... Terms whose variables |

Constant | is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. |

Linear Equation | an equation between two variables that gives a straight line when plotted on a graph.. |

Nonlinear equation | In physics and other sciences, a nonlinear system is the opposite of a linear system, that is a system that does not satisfy the superposition principle, which means that the output is not directly proportional to the input |

Quadratic | involving the second and no higher power of an unknown quantity or variable.: "a quadratic equation". |

Function | a relationship or expression involving one or more variables.: "the function (bx + c)". |

Inequality | difference in size, degree, circumstances, etc.; lack of equality.: "social inequality" "the widening inequalities in income". |

Slope | The Slope (also called Gradient ) of a straight line shows how steep a straight line is. |

Quadrant | Any of the 4 equal areas made by dividing a plane by an x and y axis |

Coordinate Plane | The Plane containing the "x" axis and "y" axis. See: Axis (graph) Cartesian Coordinates |

Standard Form | Another name for "Scientific Notation", where a number is written in two parts: |

Slope-Intercept Form | The General Form is not always the most useful Form, and you may prefer to use: The Slope-Intercept Form of the equation of a straight line: |

Variable | A symbol for a number we don't know yet. It is usually a letter like x or y. Example: in x + 2 = 6, x is the Variable If it is not a Variable it is called a Constant See: Constant |

X- intercept | X- intercept x Intercept of a Straight Line The x Intercept of a straight line is simply where the line crosses the Y axis. |

Y-Intercept | Y Intercept of a Straight Line The Y Intercept of a straight line is simply where the line crosses the x axis. |
