MODEL: Unit 1 Distributive Property DEFINITION: THE DISTRIBUTIVE PROPERTY SAYS THAT MULTIPLYING A NUMBER BY A GROUP OF NUMBERS ADDED TOGETHER IS THE SAME AS DOING EACH MULTIPLICATION SEPARATELY.

MODEL: 14, -3, -1, 7, 0, -1 Unit 1 Integers DEFINITION: A POSITIVE OR NEGATIVE WHOLE NUMBER.

MODEL: Unit 1 Intersecting DEFINITION: WHEN TWO FIGURES CROSS OR SHARE AT LEAST ONE POINT.

MODEL: Unit 1 Irrational Numbers DEFINITION: A REAL NUMBER THAT CAN NOT BE MADE BY DIVIDING TWO INTEGERS.

MODEL: Unit 1 Laws of Exponents DEFINITION: WHENEVER WE HAVE VARIABLES WITH EXPONENTS, AND THE SAME BASES, WE CAN EXPAND OR SIMPLIFY USING A FEW RULES.

MODEL: 3X AND 5X 2AB AND -8AB Unit 1 Like Terms DEFINITION: TERMS THAT HAVE THE SAME VARIABLE COMBINATION.

MODEL: 1, 2, 3, 4, 5,… Unit 1 Natural Numbers DEFINITION: WHOLE NUMBERS COUNTING UP BY ONE, STARTING AT 1.

MODEL: Unit 1 Perfect Cubes DEFINITION: NUMBERS WHOSE CUBE ROOT IS A WHOLE NUMBER.

MODEL: Unit 1 Perfect Squares DEFINITION: A NUMBER WHOSE SQUARE ROOT IS A WHOLE NUMBER.

MODEL: Unit 1 Power DEFINITION: ANOTHER NAME FOR AN EXPONENT. THREE IS RAISED TO THE POWER OF 2 MEANS 3 2.

MODEL: Unit 1 Radicand DEFINITION: THE VALUE UNDER THE RADICAL SIGN.

MODEL: Unit 1 Rational Numbers DEFINITION: A NUMBER THAT CAN BE MADE INTO A FRACTION OR RATIO.

MODEL: Unit 1 Real Numbers DEFINITION: THE TYPE OF NUMBER WE NORMALLY USE, SUCH AS 1, 15.82, −0.1, 3/4, ETC. POSITIVE OR NEGATIVE, LARGE OR SMALL, WHOLE NUMBERS OR DECIMAL NUMBERS ARE ALL REAL NUMBERS.

MODEL: A SHORTER WAY OF SAYING SQUARE ROOT. Unit 1 Root DEFINITION: THE SMALLEST FACTOR THAT IS MULTIPLIED BY ITSELF A NUMBER OF TIMES TO GET THE ORIGINAL NUMBER.

MODEL: Unit 1 Scientific Notation DEFINITION: A WAY TO REPRESENT A VERY LARGE OR VERY SMALL NUMBER.

MODEL: Unit 1 Square Root DEFINITION: A NUMBER THAT WHEN MULTIPLIED BY ITSELF, GIVES THE ORIGINAL NUMBER.

MODEL: 3, ,230,000 Unit 1 Standard Form of a Number DEFINITION: THE REGULAR WAY WE ARE USED TO WRITING A NUMBER.

MODEL: 1.5 Unit 1 Terminating Decimal DEFINITION: A DECIMAL THAT ENDS.

MODEL: Unit 1 Repeating Decimal DEFINITION: A DECIMAL THAT REPEATS A SET PATTERN FOREVER.

MODEL: TRUNCATED AT THE HUNDREDTHS PLACE IS Unit 1 Truncate DEFINITION: TO END A NUMBER AT THE GIVEN PLACE VALUE.

MODEL: 0, 1, 2, 3, … Unit 1 Whole Numbers DEFINITION: NUMBERS THAT ARE NATURAL PLUS 0.
