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

Coefficient | number the precedes the multiplication sign in a powers of ten equation. If no number is used in this position, the coefficient is 1 |

Base number | is the number the coefficient is being multiplied by. |

Exponent | indicates how many times the base number is mutiplied by itself. |

When does the exponent increase? | the exponent increases by 1 for each place the decimal point moves to the left. |

When does the exponent decrease? | the exponent decreases by 1 for each place the decimal point moves to the right. |

What is a unit? | 1=10^1 |

What is a kilo=k? | 1,000=10^3 |

What is a Mega=M? | 1,000,000=10^6 |

What is a Giga=G? | 1,000,000,000=10^9 |

What is a mili=m? | 0.001=10^-3 |

What is a micro=u? | 0.000001=10^-6 |

What is a nano=n? | 0.000000001=10^-9 |

What is a pica=p? | 0.000000000001=10^-12 |

What is the basic rule for adding or subtracting with exponent values? | Exponents must be the same 2x10^3 + 4x10^3 |

What is the rule for multiplying exponents? | Add the expononent values and then multiply by the numerical coefficients. 3x10^5 x 2x10^2 |

What is the rule for dividing coefficients? | First subtract the exponent values and then divide the numerical coefficients. 6x10^5 / 3x10^2 now is 6/3=10^3 ending result 2x10^3 |
