# Algebra

### Unit 1

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

Algebra | The branch of mathematics that deals with relationships between numbers, utilizing letters and other symbols to represent specific sets of numbers, or to describe a pattern of relationships between numbers. |

Binomial Expression | An algebraic expression with two unlike terms. |

Capacity | The greatest volume that a container can hold. |

Circumference | The distance around a circle. |

Coefficient | A number multiplied by a variable. |

Constant Term | A quantity that does not change its value. |

Expression | A mathematical phrase involving at least one variable and sometimes numbers and operation symbols. |

Factor | When two or more integers are multiplied, each integer is a factor of the product. "To factor" means to write the number or term as a product of its factors. |

Integer | The set of numbers...-3,-2, -1, 0, 1, 2, 3,... |

Irrational number | A number whose decimal form is non-terminating and non-repeating. Irrational numbers cannot be written in the form a/b, where a and b are integers (b cannot be zero). So all numbers that are not rational, are irrational. |

Monomial Expression | An algebraic expression with one term. |

Perimeter | The sum of the lengths of the sides of a polygon. |

Polynomial function | A polynomial function is defined as a function: f(x)=.......... , where the coefficients are real numbers. |

Pythagorean theorem | It is a theorem that states a relationship that exists in any right triangle. If the lengths of the legs in the right triangle are a and b, and the length of the hypotenuse is c, we can write the theorem as the following equation: a^2 + b^2 = c^2 |

Radical | The symbol, b square root of a, which is read "the bth root of a," is called a radical. |
