Number System
|
rational
integers whole numbers natural numbers irrational numbers percent decimal cardinals #'s Ordinal #'s |
|
Rational Numbers
|
can be expressed as ratio of two integers a/b not equal to 0
can be shown on the number line |
|
Integers
|
positive & negative whole #'s and zero (-2,-1,0,1,2)
|
|
Whole numbers
|
natural numbers and zero (0,1,2,3,4,5)
|
|
Natural Numbers
|
Counting #'s (1,2,3,4,5,6)
|
|
Irrational numbers
|
Real numbs that cannot be written as a ration of two numbers
cannot be shown on the number line |
|
Percent
|
Per 100
base 10 positional system for numbers |
|
Decimal
|
numbers written with a whole number decimal part and not decimal part
|
|
Cardinal numbers
|
counting numbers
|
|
ordinal numbers
|
indicate order of things in a set
do not show quality only position 1st, 2nd, 3ed, |
|
Commutative Property
|
order of factors and terms does not matter in addition and subtratction problems, answer will stay the same
4+2=6 2+4=6 4x2=8 2x4=8 |
|
Associative
|
Terms can be regrouped
(addition, multiplication) |
|
Identity Property
|
a term that when added (0) term results in that #
a term when multiplied by (1) equals that number |
|
Inverse Property
|
added results in 1 or
multiplied results in 0 |
|
GCF
|
the GREATEST COMMON FACTOR that two or more terms can be divided by
|
|
LCM
|
the least common multiple of two or more factors
|
|
Deductive Thinking
|
making a conclusion based on other statements that are true
|
|
inductive thinking
|
finding a pattern from a group of examples
|
|
Valid Argument
|
Deductive argument in which the conclusion necessarily follows from the premises
|
|
Conditional Statement
|
If p then q.... (p.. hypothesis q=conclusion)
|
|
Inverse Statment
|
if ~p then ~q (negate both hypothesis and conclusion
if not p and than not q |
|
Converse Statement
|
if q than p
revers 2 clauses: original hypothesis becomes conclusion and vise-vera |
|
Contrapostiive statment
|
if ~p than ~q above then negate both hypothesis and new conclusion
|
|
Proportions
|
solve word problems with compared relationships
|
|
Linear Relationship
|
two quantities are proportional (double x also doubles Y)
|
|
Non-Linear Relationship
|
relationship which change separately
one quantity does not effect other quantity to same extent |
|
Commutative Property example
|
a+b= b+a
|
|
Associative Property Example
|
(a+b)+c= a=(b+c)
|
|
Distributive Property Example
|
a(b+c) = ab=ac
|
|
Additive Identity
|
a+0=a
|
|
Multiplicative Identity
|
a X 1=a
|
|
Additive Inverse
|
a+a=0
|
|
Multiplictive Inverse
|
a X 1/5=1
|
|

|
a simple closed surface and all point in its interior
|
|
Transformation
|
change in position shape or size
|
|

|
|
translation
|
slides object a fixed distance in a given direction.
|
|
Dilation
|
transformation that shrinks object or makes it bigger
|
|
tessellation
|

|
no
ex: l=2 w=2 perimeter= 8 area = 4 l=1 w=3 perimeter= 8 area= 3 |
