# Algebra - Expression

### vocabulary from sixth grade algebra unit

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

base | A number/variable to be raised to a power/exponent. Ex. 3 is the base in the power 6^3 |

coefficient | The number (numerical factor) in front of a variable in an algebraic term. |

combining like terms | A mathematical process used to simplify an expression by using operators to unite like terms. |

constant | A term that contains only a number in an algebraic expression. |

cubed number | A number raised to the third power. Ex. 2^3= 2 x 2 x 2 = 8 |

exponent | A number that indicates the number of times the base appears as a factor. Ex. 3 is the exponent in 2^3; 2^3 = 2 x 2 x 2 (there are 3 twos being multiplied). |

expression | A mathematical phrase containing numbers, variables, and at least one operation. |

factor | Numbers that are multiplied to get a given number. Ex. 1, 2, 3, and 6 are all factors of 6 |

like terms | Terms that contain the same variables raised to the same power; only the coefficients are different. |

operator | A symbol that shows an operation. |

order of operations | Order mathematical operations should be completed. GEMA: Grouping symbols, Exponential operations, Multiplicative operations, Additive operations. |

product | The result when two numbers are multiplied. |

squared number | A number raised to the second power. Ex. 5^2= 5 x 5 = 25 |

terms | Any part of an expression written as a product or quotient; they are separated by the additive operations. |

variable | A symbol used to represent a number. This variable can change or take on different values. |

Evaluate | Find the value of by substituting a value in place of the variable(s) and then simplify. |

Simplify | Writing an expression in the most compact way without changing the value. |
