Back 11

indicate order of things in a set
do not show quality only position
1st, 2nd, 3ed,

Front 12

Commutative Property

Back 12

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

Front 13

Associative

Back 13

Terms can be regrouped
(addition, multiplication)

Front 14

Identity Property

Back 14

a term that when added (0) term results in that #
a term when multiplied by (1) equals that number

Front 15

Inverse Property

Back 15

added results in 1 or
multiplied results in 0

Front 18

Deductive Thinking

Back 18

making a conclusion based on other statements that are true

Front 19

inductive thinking

Back 19

finding a pattern from a group of examples

Front 20

Valid Argument

Back 20

Deductive argument in which the conclusion necessarily follows from the premises

Front 21

Conditional Statement

Back 21

If p then q.... (p.. hypothesis q=conclusion)

Front 22

Inverse Statment

Back 22

if ~p then ~q (negate both hypothesis and conclusion
if not p and than not q

Front 23

Converse Statement

Back 23

if q than p
revers 2 clauses: original hypothesis becomes conclusion and vise-vera

Front 24

Contrapostiive statment

Back 24

if ~p than ~q above then negate both hypothesis and new conclusion

two quantities are proportional (double x also doubles Y)

Front 27

Non-Linear Relationship

Back 27

relationship which change separately
one quantity does not effect other quantity to same extent
