1
Whole Numbers. Numbers like 0,1,2,3…. Example: 2 + 4 = 6
2
Integers. Are the numbers –3,-2,-1,0,1,2,3…. Example: -2 + -3= -5
3
Rational numbers. Is a number a/b where a and b are integers and b does not equal 0. Example: -1/2 is a rational number because it can be written as –1/2 or 1/-2
4
Opposites. Two numbers that are the same distance from 0 on a number line, but are on opposite sides of 0. Example: 4 and –4 are opposites because they are both 4 units from 0, but on opposite sides of 0.
5
Absolute value. A number a is the distance between a and 0 on a number line. The symbol |a| represents the absolute value of a.
6
Additive identity. The identity property states that the sum of a number a and 0 is a. The number 0 is the additive identity.
7
Additive inverse. The inverse property states that the sum of a number a and its opposite is 0. The opposite of a is its additive inverse.
8
MULTIPLACTATIVE IDENTITY MULTIPLICATIVE IDENTITY A NUMBER THAT IS 1 OR A PRODUCT OF A NUMBER a IS a
9
EQUIVALENT EXPRESSIONS TWO EXPRESSIONS THAT HAVE THE SAME VALUE FOR ALL VALUES OF THE VARIABLE.
10
DISTRIBUTIVE PROPERTY The equation 3(x+2)=3(x)+3(2) Which can be used to find the produce of a number and a sum or diffence.
11
TERMS. THE NUMBERS OF THE EXPRESSTION THAT ARE ADDED TOGETHER. EXAMPLE: -x+2x+8 TERMS=-1,2,and 8
12
COEFFICIENT The number of a term with a variable part is called coefficient of the term. Terms –x+2x+8 the coefficient is the -1 and 2
13
CONSTANT TERMS The constant term has a number part but no variable part. Such as 8 in the expression below -x+2x+8
14
LIKE TERMS LIKE TERMS ARE TERMS THAT HAVE THE SAME VARIABLE PART, SUCH AS –x AND 2x IN THE EXPRESSION -x+2x+8
15
MULTIPLACATIVE INVERSE
16
SQUARE ROOT THE NUMBER YOU MULIPLY BY ITSELF TO GET THE NUMBER UNDER THE RADICAL SYMBOL.
17
RADICAND THE NUMBER OR EXPRESIONS INSIDE A RADICAL SYMBOL IS THE RADICAND.
18
PERFECT SQUARE THE SQUARE OF AN INTERGER IS CALLED A PERFECT SQUARE.
19
IRRATIONAL NUMBERS IS THE NUMBER THAT CAN NOT BE WRITTEN AS A QUOITIENT OF TWO INTERGERS.
20
REAL NUMBERS IS A SET OF ALL RATIONAL AND IRRATIONAL NUMBERS.
