Algebra : | A branch of mathematics that substitutes letters for numbers. An algebraic equation represents a scale, what is done on one side of the scale with a number is also done to the other side of the scale. The numbers are the constants1. |

Algorithm : | A step-by-step problem-solving procedure for solving computational mathematical problems. |

Angle : | Angles are formed by two rays that begin at the same point. |

Arc : | A section or portion of the circumference of the circle. |

Area : | The space measured in square units that any 2 dimensional shape or polygon occupies. |

Arithmetic : | A branch of mathematics usually concerned with the four operations (adding, subtracting, multiplication and division) of positive numbers. |

Array : | A set of numbers that will follow a specific pattern. An orderly arrangement often in rows, columns or a matrix. |

Attribute : | A characteristic to describe an object usually within a pattern. The attribute usually refers to the shape, size, or color. |

Average : | The middle or most common in a set of data. There are three types of average in mathematics - the mean, the median and the mode. |

Axis : | The vertical and horizontal lines that make up the quadrants of a coordinate plane. The vertical axis is usually referred to as the y axis and the horizontal axis is usually referred to as the x axis. |

Absolute Value : | Definition: Always a positive number refers to the distance of a number from 0, the distances are positive. Examples: You will use this term to refer to the distance of a point or number from the origin (zero point) of a number line. The symbol to show th |

Acute Angle : | Definition: The measure of an angle with a measure between 0° and 90° or with less than 90°radians. Also Known As: A positive angle that measures less than 90° |

Addend : | Definition: A number which is involved in addition. Numbers being added are considered to be the addends. Also Known As: 3+2=4 The three and the two are the addends. In the expression a + b+c the a,b, and c are also referred to as the addends. Ex |
