# chapter 2

term | definition/example | example |
---|---|---|

base | when a number is written in exponential form, the number that is used as a factor is the base. | 5^2 5=base |

composite number | a number greater than 1 that has more than two factors | 4 = composite number |

equivalent fractions | equivalent fractions are fractions that name the same amount | 1/2 and 2/4 are equivalent fractions |

factor | a whole number that divides another hole number with a remainder of zero | 1,2,3,4,6,12,18,and 36 are all factors of 36 |

greatest common factor (GCF) | the greatest common factor is the greatest factor that two numbers share | the GCF of 12 and 30 is 6 |

improper fraction | the numerator is larger than the denominator | 45/3 is an example of an improper fraction |

exponent | an exponent is how many time a base is multiplied by it self | 5^2 2 = exponent |

least common multiple (LCM) | the least multiple between two numbers | the LCM of 10 and 20 is 20 |

mixed number | a mixed number is the sum of a whole number and a fraction | 3 1/2 is a mixed number |

multiple | a number that is the product of that number and any nonzero number | 39 is a multiple of 13 |

power | a number that can be expressed using an exponent | 3^4, 5^2, and 2^10 are powers |

prime factorization | In number theory, integer factorization or prime factorization is the decomposition of a composite number into smaller non-trivial divisors, which when multiplied together equal the original integer | the prime factorization of 12 is 2x2x3 or 2^2x3 |

prime number | a number that is only divisible by two numbers 1 and itself | 1 and 13 are examples of prime numbers |

rational number | a number that can be written as a quotient of two integers, where the divisor | 1/3, -5, 6.4, 0.666..., -24/5, 0, and 7/3 are rational numbers |

repeating decimal | a decimal that repeats with out end | 0.888... is a repeating decimal |

scientific notation | a number that is written as the product of two factors | 37,000,000 is written as 3.7x10^7 in scientific notation |

simplest form | a fraction is in simplest form when the numerator and denominator have no common factors other than one | the simplest form of 3/9 is 1/3 |

terminating decimal | a decimal that stops or terminates | both 0.6 ad 0.7265 are terminating decimals |

least common denominator (LCD) | the smallest whole number that is divisible by each of the denominators | the LCD of the fractions 3/8 and 7/10 is 40 |
