Mathematics learning involves a clear understanding of concepts and knowledge of simple problem-solving techniques. It requires proper guidance from teachers and other experts who can clarify the concepts on various topics of mathematics. The guidance can be available in online mode through the math blogs written by different people having a strong base in mathematics. The purpose of writing blogs is to make students learn basic concepts or enhance their knowledge of specific mathematics topics. It can be good support for students to clear out certain doubts that are being taught in the classroom. Students can find many math blogs on the internet that guide them on various aspects of mathematics learning.

**What are the Types of Blogs**

Mathematics blogs are written by teachers or academic experts to represent various topics interestingly that can draw the attention of students. It includes simple illustrations, real-life examples, and solved problems to help students understand the concepts. The blogs aim to provide some new knowledge interestingly, to make it more appealing to students so that they become more involved in reading these blogs. Math blogs can help enhance mathematical skills that also make students confident and motivated. The blogs involve an explanation of topics with clear examples, step-by-step processes, and practice problems. Some blogs are published online as a series of structured learning modules that help students to enhance their knowledge and skills.

**Essential Benefits of Blogs**

There are several mathematics blogs available online for students starting from kids to students of higher standards. The blogs are written differently unlike textbook learning but use an interactive mode with clear language that allows users to follow concepts easily. It is a great opportunity for students to get guidance and suggestions from expert mentors through their blogs without paying any fees. Math blogs have become quite popular among students to get their doubts clarified and learn new concepts. These blogs are found to be an effective online resource for learning mathematics by getting to learn some practical approaches based on the experience of experts.

**Domain And Range: Maths Concepts Based on Functions**

The domain and range are the important concepts of mathematics that are related to functions. The domain is the set of input values and the range is the set of output values of the function.

**What is the Domain of a Function**

The domain of a function is all the possible input values for that function. Suppose there is a function f(x) = x + 10. Now the value of x can be any natural number like 1,2,3,4,…etc. The set of input values is called the domain of this function. We can say, the domain of this function is a set of any natural numbers.

**Range of a Function**

The range of a function is the set of all outputs of a function for a particular domain of inputs.

For example, for the function f(x) = x + 10, for every input value of natural number, we get an output of natural number. Thus we get a set of natural numbers as output each of which has a value greater than 10. Therefore, the range of this function is the set of natural numbers greater than 10.

**Relationship of Domain and Range**

The elements of a domain are called pre-images and elements of the range are called images. So, the range of a function is the set of all images of the elements of the domain. There are general formulas that are used to find the domain and range of different types of functions including exponentials, logarithmic, and trigonometric functions.
