maths
natural numbers
addition
additon is two or more numbers being put together to make a bigger number
subtraktion
factors and mulitiples
mulitiplycation
division
communitive
when the order of the sum given doesnt matter e.g.[5+6=11] and [6+5 = 11] this only works for addition and multiplycation
distribtive
diffrent or simplier way to do the sum e.g 5[4=3]=35 and [5x4]=[5x3]=35
assosiative
assosiative is when the grouping does not matter e.g [3+4] +5=3+[4+5]
order of opeations
addition subtracion muliplycation and addition
sets
subsets
venn diagrams
a venn diagram consists of three parts . the right snd left side usually have a letter or number to distingush them the middle or intersection of the set contain what the right and left side have in common
union
the union is all the numbers together
intersection
the intersection is the middle of the venn diagram it contains what the two sides have in common e.g {a=1,2,3,4} {b=2,3,4,5} 2, 3 and 4 would be in the intersection because both sides contain the componts
universal set
a universal set is the whole set including what isnt in the venn diagram
integers
addition and subtraction of intergers
muliplycation of intergers
division of intergers
order of operations
bimdas
brakcets
indices
multiplycation
division
addition
subtraction
if all of the numbers are in {a} that are in {b} we call b a subset of a
