An arrangement of objects in which the order is not important is called a combination. This is different from permutation where the order matters. For example, suppose we are arranging the letters A, B and C. In a permutation, the arrangement ABC and ACB are different.
In math, a combination is an arrangement in which order does not matter. Often contrasted with permutations, which are ordered arrangements, a combination defines how many ways you could choose a group from a larger group. Note: To understand this topic, it is highly advisable to be familiar with factorial notation.

A permutation of a set of objects is any rearrangement (linear ordering) of the objects. There are (the factorial of ) permutations of a set with distinct objects. One can also consider permutations of infinite sets. In this case, a permutation of a set is simply a bijection between and itself.Read More

This was a finding the combinations of a vector problem. And the previous one it was figure out if two lines can intersect. But what it tells you is that these two problems are connected in some deep way. That if we take the veneer of reality, that underlying it, they are the same thing. And frankly, that's why math is so interesting. Because when you realize that two problems are really the.Read More

After years of working with students in the USA we came up with unique combination of Russian Math and Singapore Math. The Russian approach to teach mathematics is when a systematic presentation of the course from K-12 goes along with the presentation of complex concepts to much younger children. Abstract concepts are introduced from the first grade (simple algebra, equations, e.t.c). Problem.Read More
