Discrete Math

Discrete math has a wide application in the modern mathematics. Discrete mathematics is generally used in decision mathematics. In this mathematics, we study about objects, set and graphs. Before studying discrete mathematics you must have knowledge of following parameters.

Matrix: In matrix, we can put any type of object in the rectangular box. These entries can be real or complex. The entries we are doing are called element of matrix. In matrix we are having rows and columns as well.

Determinate: Determinate can be found out very easily we just need to multiply element of 1^st column to the element of second column. Then we can subtract and we can find the determinate easily. Determinate can be negative or positive.

Permutations: Permutation of an object is the number of different way it can be ordered. It is mainly used for small numbers. For example, if we have to choose 6 coins out of 9 than I will use permutation for that. It is mainly of two types:

1- Permutation with repetition

2- Permutation without repetition

Combination: If we have to choose a large number of object & your way of choosing is also important than we move to combination. Like permutation, combination is also of two types:

1-Combination with repetition

2-Combination without repetition

Sequence: If we have a given set of number and we arranged the numbers in a sequence. We can arrange the number in ascending order or descending order.

Series: Series is mathematical pattern which has some relation with its upcoming member. We can say that if we have a series like 2,4,8,16 and so on then we can say that, 4/2=8/2=16/8=2. Here we can see that the common difference is 2.
