Anything that is not in A or B - ANS-A∩⁻B
Arithmetic Sequence Formula - ANS-A=a₁+(n-1)d
A= Last term
a₁=1st term
n=which term you need to know
d= common difference
Associative Property - ANS-The manner in which numbers are grouped does no longer change
their sum or product
(2+3)+4=2+(three+four) or (2*three)*4=2*(three*4)
cardinal numbers - ANS-number of a fixed is the quantity of factors in a set notation used (A) or
IAI
A=(1,2,3,five,eight,nine) IAI=6
Commutative Property - ANS-The order wherein numbers are delivered or extended does now
not exchange the sum or product.
Change locations
a+b=b+a a*b=b*a
supplement - ANS-the factors which are NOT in the stated set
Example: E' is study ''supplement of E'' and manner all of the elements which might be NOT in
E but in Universal set
A' = now not in A or B
Distributive Property - ANS-a assets indicating a unique manner in which multiplication is carried
out to addition of or greater numbers in which each term internal a hard and fast of parentheses
can be accelerated via a element out of doors the parentheses, including a(b + c) = ab + ac
Divisible by way of 3 - ANS-if the sum of the digits is divisible by means of three
divisible with the aid of 4 take a look at - ANS-If the ultimate 2 digits are divisible by using 4
divisible via 6 test - ANS-If the sum of the digits is divisible by using 2 & 3
divisible by eight rule - ANS-If the closing three digits are divisible through eight
