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

base number | a number or quantity which is arbitrarily made the fundamental number of a system; also called base |

exponent or power | Mathematics . a symbol or number placed above and after another symbol or number to denote the power to which the latter is to be raised: The exponents of the quantities x n , 2 m , y 4 , and 3 5 are, respectively, n, m, 4, and 5. |

constant | not changing or varying; uniform; regular; invariable: All conditions during the three experiments were constant. |

coefficients | a number or quantity placed (generally) before and multiplying another quantity, as 3 in the expression 3x. |

like terms | In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers |

distributive property | "multiplication distributes over addition". Formally, they write this property as "a(b + c) = ab + ac". In numbers, this means, that 2(3 + 4) = 2Ч3 + 2Ч4. |

exponential form | simply means a numeric form involving exponents. One way to write such a number is by recognizing that each position represents a power (exponent) of 10. So you can first break it up into separate pieces. |

expanded form | Expanded form is a way to write numbers by showing the value of each digit. |

standard form | Standard form is a way to write numbers using the digits 0-9. |

order of operations | In mathematics and computer programming, the order of operations (sometimes called operator precedence) is a rule used to clarify which procedures should be performed first in a given mathematical expression |
