# COMBINATION CALCULATOR

Combination calculator provided on this web page is a tool which can be used  to find number of combinations of "N" things taken "r" at a time.

## Why do people need this calculator?

Permutation and combination problems play a major role in quantitative aptitude test. It is bit difficult to score marks in competitive exams without knowing the shortcuts related to permutation and combination problems.  We might have already learned this topic in our school. Even though we have been already taught this topic in our higher  classes in school, we need to learn some more short cuts which are being used to solve problems on this topic.

The only thing we have to do is, we need to apply the appropriate short cut and solve the problems in a limited time. This limited time will be one minute or less than one minute in most of the competitive exams. When students do some difficult problems on permutation and combination, often they may have to apply trial and error method. At that time, calculating number of combinations every time would be an additional burden for the students. At that time students can use this combinations calculator.

## Using the calculator in solving word problems

When people do preparation of solving word problems on "Permutation and Combination, they may have to spend time to get idea on "How to solve". In many situations,  they may have to apply trial and error method to get correct answer. When students apply trial and error method, they  would not like to spend time to find number of combinations every time. Because, while solving some big word problems, finding number of combinations every time will annoy them.

While solving lengthy word problems, they have to do this work separately and they might do some careless mistakes in finding number of combinations. It will definitely disturb the solving of word problems on Math.  And also they would not be able to use the regular calculators to find number of combinations. By using this online calculator, students will find much time to get idea of solving the word problems.

## Advantages of using this online calculator

Students have the topic "Permutation and Combination" in school level  math. They may have to do lots of problems on this topic. In most of the problems on permutation and combination, they may have to apply trial and error method. Students would find answers for the questions as directed in the question. But they would not be sure, whether the answer they have received is correct or incorrect. At that time, they can use this calculator to verify their answer.
