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

area | The number of square units needed to cover a surface or figure. |

Associative Property of Addition | Addends can be regrouped and the sum remains the same. Example: 1 + (3+5) = (1+3) + 5 |

Associative Property of Multiplication | Factors can be regrouped and the product remains the same. Example: 2 x (4 x 10) = (2 x 4) x 10 |

Commutative Property of Addition | The order of addends can be changed and the sum remains the same. Example: 3 + 7 = 7 + 3 |

Whole Numbers | The numbers 0, 1, 2, 3, 4, and so on |

Word Form | A way to write a number using words. |

Zero Property of Multiplication | The product of any number and 0 is 0. |

tenth | One out of ten equal parts of a whole. Example: 1/10 ; (1 x 1/10); 0.1 |

thousandth | One out of 1,000 equal parts of a whole. Example: 1/1000; (1 X 1/1000); 0.001 |

underestimate | The result of using lesser numbers to estimate a sum or product. The estimate is smaller than the actual answer. |

value (of a digit) | The number a digit represents, which is determined by the of the digit. |

Commutative Property of Multiplication | The order of factors can be changed and the product remains the same. Example: 3 x 5 = 5 x 3 |

compatible numbers | Numbers that are easy to compute with mentally. |

composite number | A whole number greater than 1 with more than 2 factors. |

decimal | A number with one or more places to the right of a decimal point. |

data | Collected information. |

difference | The number that results from subtracting one number from another. |

digits | The symbols used to show numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 |

Distributive Property | Multiplying a sum (or difference) by a number is the same as multiplying each number in the sum (or difference) by the number and adding (or subtracting) the products. Example: 3 x (10+4) = (3 x 10) + 4 |

dividend | That number to be divided. |

divisible | A number is divisible by another number if there is no remainder after dividing. |

divisor | The number used to divide another number. |

standard form | A common way of writing a number with commas separating groups of three digits starting from the right. Example: 3, 485 |

sum | The number that is the result of adding to or more addends. |

remainder | In division, the number that is left after the division is complete. |

rounding | A process that determines which multiple of 10, 100, 1,000, . . a number is closes to. |

equation | A number sentence that uses an equal sign to show that two expressions have the same value. Example: 9 + 3 = 12 |

estimate | To give an approximate value rather than an exact answer. |

evaluate | To find the value of an expression. |

expanded form | A way to write a number that shows the place value of a digit. Example: 3,000 + 500 + 60 + 2 |

factors | Numbers that are multiplied to get a product. |

hundredth | One part of 100 equql parts of a whole. Example: 1/100; (1 X 1/100); 0.01 |

prime factorization | The process of writing a whole number as a product of its prime factors. |

Prime Number | A whole number greater than 1 that has exactly two factors, itself and 1. |

product | The number that is the result of multiplying two or more factors. |

quotient | The answer to a division problem. |

Place value | The position of a digit in a number that is used to determine the value of the digit. Example: In 5, 318, the 3 is in the hundreds place. So 3 has a value of 300. |

inverse operations | Operations that undo each other. Example Adding 6 and subtracting 6 are inverse operations |

multiple | The product of a given whole number and any other whole number. |

multiple of 10 | A number that has 10 as a factor. |

overestimate | The result of using larger numbers to estimate a sum or a product. The estimate is larger than the actual answer. |

numerator | The number above the fraction bar in a fraction. |

denominator | The number below the fraction bar in a fraction. |

order of operations | Order in which operations are done in calculations. Work inside parentheses or brackets first. Next, exponents evaluated. Then multiplication and division are done from left to right. Finally addition and subtraction in order from left to right. (GEMDAS) |
