### integers

Question | Answer |
---|---|

Integers | The whole numbers and their opposites form the set of integers |

Opposites | Opposites are two integers the same distance from zero on a number line, but in opposite directions |

Absolute Value | The absolute value of an integer is the distance from zero on a number line |

= | is equal to |

< | is less than |

> | is greater than |

Sum | answer in an addition problem |

Difference | the answer in a subtraction problem |

Product | the answer in a multiplication problem |

Quotient | The answer in an division problem |

Adding two integers with the same sign | Add the absolute values of the integers. The sum has the same sign as the addends |

Adding two integers with different signs | Find the difference (of the absolute value of the addends). The sum has the sign of the integer with the greatest value. |

Subtracting integers | Add its opposite |

Multiplying integers with the same sign | Find the product and give it a positive sign |

Multiplying integers with different signs | Find the product. The product of different signs is always negative |

Dividing integers with same signs | The quotient of two integers with the same sign is positive |

Dividing integers with different signs | The quotient of two integers with different signs is negative |

What is the mean? | The mean is the average you see most ofter |

Finding the mean | 1. Find the sum of the numbers 2. Divide the sum by the number of items |

Variable | is a symbol (usually a letter) that stands for a number |

Variable expression | is an expression (number sentence) that contains at least one variable |

Grouping symbols | (Parentheses) [brackets] and Iabsolute valueI |

Order of Operations | PEMDAS: Parenthesis, exponents,Multiply, Divide, Add. Subtract |

From which direction do you work a problem | Left to Right, from the inside out |

Factor | the numbers you are multiplying to get a product |

Divisibility Test | short cuts for finding factors of whole numbers |

A number is divisible by 2 if... | the last digit is an even number |

A number is divisible by 3 if... | the digits add up to 3,6,or 9 |

A number is divisible by 5 if... | the last digit is 0 or 5 |

A number is divisible by 10 if ... | the last digit is 0 |

Prime number | a whole number greater than 1 that has only 1 and itself as factors |

Composite number | A whole number greater than 1 that has at least one factor besides itself and 1 |

Prime Factorization | Every composite number can be expressed as a product of only prime numbers |

Base number | a base number is a number used as a factor |

Exponent | is the number of times the base number is used as a factor |

Power | is a number that can be writted using an exponent |
