Binomial Theorem is a way of expanding a given equation and simplifying it. We break the given equation in many different fragments based on the power. The useful application for Binomial Theorem is that when the equation's power increases, the calculation work becomes tedious. It is not easy to calculate the value of (x + y4)13 easily as that would take a long time. But by using binomial theorem, we can quickly calculate its value. Binomial Thoerem is used in Algebra, Probability and Calculus.
In CAT and other MBA entrance exams, questions on Binomial Theorem appear in Quantitative Aptitude section. The questions are usually of moderate difficulty level. To prepare Binomial Theorem for CAT or any other entrance/competitive exam, one needs to understand the fundamentals. Read here all about Binomial Theorem.

What is Binomial Theorem?
Binomial theorem as explained above is a method of expanding an expression that has been raised to any finite power. A binomial theorem has applications in Algebra, probability, etc. Whenever an equation has been raised to high powers, it is difficult to simplify it and get the answers. Hence, we simplify the equation by breaking it into parts of each power, starting from 0. In the binomial theorem, there are 2 variables that get expanded. When more than two variables are used in expansion, then it is called multinomial expansion. Multinomial expansion follows a different technique.

Parts of Binomial Theorem
Any binomial expansion has different terms as the power of a variable and consonant keeps increasing from 0. Hence binomial expansion sees the use of permutation and combination concepts. Some terminologies used in the binomial expansion are:
- General term
- Middle term
- Independent term
- Numerically greatest term
- Ratio of consecutive terms

What are the Different Types of Arithmetic Operations?
The binomial theorem can be classified based on the power for which it is expanding. Some of the major categories are:
- Binomial Theorem for Rational Index
- Binomial Theorem for Negative Index
- Multinomial Theorem (more than three variables in the equation)
- Pascal's Triangle
