Complex Numbers are nothing but nightmare to a considerable number of students as the issues related to it are really complex or at least not easy. But the opinion is not same for everyone. It is not very hard to another considerable chunk of student. Actually, the matter is that it is you who will decide your faith, it is up to you whether you can make it easy for you or not. The bone of contention is your concept. If your concept is crystal clear then complex numbers are not hard for you, but if you are struggling with concept then you are not at home in it. Anyway, if you have capability of building concept by yourself then I have a number of websites where you can get materials for concept building. Websites are given below:

Probability is a part of Statistics that is a specific branch of Mathematics. We use probability to determine the degree of certainty and the uncertainty of a particular event.

Actually it is nothing but a set of predefined mathematical principles and techniques that help us to establish the probability of an event. Probability can be used to solve the real life problems. Let’s have a look on an analogy. Consider we have to toss a coin that has two sides head and tail. You have to call either head or tail. You are determined to call head. Do you know, what is the probability of your win? It is very simple to determine. Probability of your win simply means the probability of getting head. According to the formula it is 0.5.

Thus, learning probability can be a great fun as it is very easy to learn and applicable to real life problems. Practicing probability helps us to develop logical thinking that is very important in real life and that is why you will find it in the syllabuses of almost all competitive examinations. If you are interested then you can get lots of study materials from various websites. Some popular websites where you can get tutorials for probability are given below:

Most of us are afraid of mathematics as we need to develop high skill in logical thinking and have to go through constant practices to master this subject. Anyway, it is one of the most important subjects and is so called mother of science. Every pure science subject is dependent on math either directly or indirectly. Anyway, lots of interesting facts can be found in mathematics which is really very interesting. Have a look on the following examples:

1. 2 is the only prime number which is an even number.
2. The largest known primes are ones of the forms (2^m - 1).
3. 1 x 9 + 2 = 11
   12 x 9 + 3 = 111
   123 x 9 + 4 = 1111
   1234 x 9 + 5 = 11111
   12345 x 9 + 6 = 111111
   123456 x 9 + 7 = 1111111
   1234567 x 9 + 8 = 11111111
   12345678 x 9 + 9 = 111111111
   123456789 x 9 +10= 1111111111
4. 1 x 1 = 1
   11 x 11 = 121
   111 x 111 = 12321
   1111 x 1111 = 1234321
   11111 x 11111 = 123454321
   111111 x 111111 = 12345654321
   1111111 x 1111111 = 1234567654321
   11111111 x 11111111 = 123456787654321
   111111111 x 111111111=12345678987654321
5. 111,111,111 x 111,111,111 = 12,345,678,987,654,321
6. Choose any prime number greater than 3.  Then square that number and add 14. Now divide it with 3. The remainder will always be 3.

Calculus, one of the easiest and the most scoring papers of mathematics, seems to be too hard for a large number of students due to lack of concepts and enough practice. If you want to be at the home in calculus then the foremost thing you need to do is, developing a crystal clear concept on it and for that you need a number of good notes and huge practice. If you are one of the students who are not comfortable with calculus and feel that you are at the sea in it, then Paul’s online notes are tailor made for you.
The address of this tutorial is http://tutorial.math.lamar.edu
Actually this online tutorial is the e-versions of the set of lectures that Mr. Paul delivers at Lamar University. These notes are not tainted with useless statements and focus on developing the crystal clear concepts. Along with the theories, numerous problems followed by detailed solutions are also provided to make your concepts more firm and flawless. You can download the whole set or the specific parts of available notes to use them when you are not connected to Internet.
