MATH TEST 

**im gonna cry.**

TERM 1 = MASTERY EXAM AND QUIZ im gonna sob

\:DD review review lang

\
LAS 1 :

**set** = a term that ==describes the collection== of distinct ==objects or items== that have something

in ==common==

\
DISTINCTION OF WELL DEFINED SET AND NON WELL-DEFINED SET :

\: A well-defined set is a set that doesn’t need or doesn’t have an opinion.

EX. = The set of ==RED== apples / The set of ==BLUE== Tshirts

\: A non well-defined set is a set that has a opinion in their set (?)

EX = The set of ==TALL== teenagers / The set of all ==OLD== people

( this is a non well-defined set because this set has the perspective of the viewer )

\
**LAS 2 :**

@@Roster method and Set building notation@@

\
@@Roster Method:@@ this is the Listing method. Listing the elements of the set.

( ex. = Set of odd numbers / A = ( @@3 , 5 , 7 , 9 …@@ ) )

Set Building notation method: A @@method that lists the rules@@ that @@determine whether@@ an object is an element of the set or @@simply describes elements.@@

**You basically describe the elements in the Set Building Notation**.

\
( ex. = D = ( 2 , 4 , 6 , 8 , … ) / @@The set of all even numbers.@@ )

**LAS 3 / 4 :**

Subset/s ( putangina )

Proper Subset : **pag may kulang na isa** (parang ikaw hahahah)

ex . = A ( 1 , 2 , 3 , 4 ) is the subset of B = ( 1 , 2 , 3 , 4 , 5 )

\
Power of the set :

\
formula : 2 r ( r is the number of elements in the set )

ex. 2 to the 2nd power or 2 by 2 squared is 4

= 2 ‘2 = 2x2 = 4

= 4 elements shi idk ( 4 ung answer )

\
**%%SET OPERATIONS MWAUAHAHAH :%%**

%%Union set :%% add mo ung set A at set B

**%%based on the given%%**

Intersection set: you add the elements of the intersection of set A and set B

**based on the given**

%%Complement set :%%

is the set of all the elements in the universal set (U) that is not in Set A.

%%Difference of two sets:%%

is the set that contains all the elements that are in A but not in B.
