Probability is the possibility of some events to happen or the belief that something will happen.
What is probability in Math?
In Mathematics, when you do an experiment the possibility of getting some results is called probability.
For example, there is probability of getting 6 in tossing a dice.
Calculating probability formula: If there is a set of N elements , we can define a sub-set of n favorable event where n is less than or equal to N.Then probability is calculated as P = n/N. All the other formula of probability are derived from this formula.
Next time we will learn how to solve probability problems using the above formula with many examples.

Elementary Math help
In elementary Math, basic arithmetics such as addition, subtraction, division and multiplication are included.Elementary Math is taught to students of lower grades.
Learning elementary Math is very important as all the basics that are needed for higher Maths is given here.You can avail elementary Math help where you will also get elementary algebra help.
In elementary algebra, you will be provided with lots of solved problems on algebra.Online help on elementary Math that covers all the basic concepts are also available in many websites.

Solving linear equations
Linear equation is an algebraic expression in which each terms has degree not more than 1. Linear equation can have one or more variables.
A linear equation can be written as y = m + bx, where m and b are constants.
Let's solve linear equations by taking some examples.
Find x if 4x - 4y = 8
Soln.4x = 8 + 4y
4x/4 = 8/4 + 4y/4
x = 2 + y
substituting the value of x in the initial equation, we get
8 + 4y - 4y = 8
8 = 8

Least Common Multiples
What are common multiples?
Multiples that are common to two or more numbers are called common multiples.
Least common multiple: The least common multiples are the smallest numbers that are both the common multiples of the numbers.
How to find least common multiple?
Let us find the least common multiple of 4 and 6
Multiples of 4 are 4, 8, 12, 16, 20, 24,......
Multiples of 6 are, 6, 12, 18, 24, 30,......
The common multiples of 4 and 6 are 12, 24,..
Since 12 is the smallest multiple for both 12 is the least common multiple of 4 and 6.

Learn sequence and series
A sequence is a set of numbers that are in order.For example, 1,2,3,4,5,6,7,8,9.....is a sequence.The dots indicate that the sequence is infinite.If there are no dots in a sequence , it is a finite sequence.
We get a series when we sum up the terms of a sequence.For example, 1+2+3+4+5+.....is an infinite series.
There are websites where you can avail basic information on sequence and series.
Many sequence and series help are available online from different tutoring company.You can get contact for
live tutor as well at your local area .

Polygon
Polygon is a closed figure made up of several line segments that are joined together.The sides meet at vertices, they do not cross each other.
There are five types of polygon.They are regular polygon, equiangular polygon, equilateral polygon, concave polygon and convex polygon.
The area of a polygon is calculated by the formula, A = (1/2)N sine(360degree/N)S^2
where N is the number of sides and S is the length from center to a corner.
Next time we will learn the different types of polygon in detail.

Prime numbers
Let's learn what is a prime number.
A prime number is a number that can be divisible only by 1 and itself.
For example, 3 and 5 are prime numbers because they can only be divisible by 1 and themselves.
Let's list prime numbers between 1 to 10.
The prime numbers between 1 to 10 are 3, 5 and 7.
Similarly, you can find out prime numbers from number between 1 to 100.
