Factors | Factors are what goes into the numbers. |

Order of Operations | PEMDAS |

Exponent | 3^2= 3x3= 9 |

Base | The base is the whole number |

Power | The power is the number above the base |

(-3)² means | (-3)x(-3)= 9 |

-3² means | 3x3= -9 |

Prime Numbers | A prime number is a whole number that only has two factors which are itself and one. |

Composite Numbers | All even numbers are composite including 0 |

GCF | Greatest Common Factor |

Variable GCF | x^2y^5, xy^3 |

Prime Factorization | 120 |

Finding Prime Factorization using GCF | 78 and 124 do a factor tree |

Simplifying Variable expressions | 12x^2y^5/8x^4y^2 |

Rational Numbers | A number that can be simply put into a fraction |

Negative Rational Numbers | 4x^3y^5 * 3x^2yz^2 |

Power of Power Rule | (x^3y^5)^4 |

Zero exponent Rule | x^0 |

Negative exponent Rule | x^-3 |

Write without negative exponents | x^-3y^2/a^2b^-3 |

Rewrite without a fraction bar | x^3y^2/a^2b^3 |

Rewrite without zero or nagative exponents and simplify | x^-2y^2z^0/x^-2y^-3 |
