Microeconomics studies the economic behavior of individual decision-makers. To be able to make sound decisions in economics, the economist has designed mathematical models based on the differentiation of simple functions. Economics and mathematics are directly related as changes in quantities and variables affect the relationship and the direction of the consumer behavior to become better –off or worse-off. The main objectives of this study are microeconomic theories that may simplify or easily understandable through the mathematical calculation to illustrate the examples and calculate the equilibrium positions numerically. The study also aims to provide mathematical tools that manage to determine all the information necessary for decision making from a broad vision. The relationship between quantity and price may be better explained through mathematical notations. The supply and demand curve is designed to find the equilibrium point and it is better explained through mathematical equations. To explain, the methodology is used for a simple mathematical function of price with the help of a simple linear and nonlinear model of static analysis of the market equilibrium of Qd=Qs. This study concludes that it will greatly help college students, professionals, entrepreneurs, and in general anyone presents solved exercise and proposes problems, for the student to solve cases create graphs, table, and interpret and analyze results in the market and thus fixing the knowledge.

COVID-19 has changed the way people around the world change their daily lives. Such a change took place not only in developed countries but also in developing countries. Such daily changes took place in the educational sector of the country as well as in other sectors. As a result, Saraswati Multiple Campus also changed its old academic calendar to conduct online classes. This article aims to inform all about the online classes conducted by Saraswati Multiple Campus during the lockdown period of COVID-19. This article is descriptive. However, in general, 60 students have been asked three questions each online and the data has been collected and explained based on that. Similarly, the general method for interpreting online classes is based on online information published by Tribhuvan University at different times, online information published by the campus administration, and various online related articles. Also, the summary of this article says that the online class conducted by the campus has been effective despite various problems.

In our teaching program and methods, the mathematical approach has a major influence on economics. In this paper, I examined the aforementioned economics and mathematical relationships, taking into account their historical development as well as the experience gained over several years in the Masters in Economics Sciences' economics course. Changes in the initial practices in the classroom entering university have prompted a rethinking of a number of fundamental questions, including: What parameters should be used to determine the most suitable curriculum and teaching approach in a changing environment? What mathematical singularities does economics teaching present? This last question introduces us to the topic we'll be discussing. How much math should be taught in economics classes? Is it important for students to have a strong mathematical foundation before they study economics? For some teachers, economic issues are merely an addendum to the practical portion of the topic, while for others; economic models are the subject's main focus. As a consequence, mathematics in general is now assisting in the analysis of economics. In conclusion, as students study economics, it becomes more difficult for them to study other mathematics topics. Since not all students excel at math, economics is a more difficult subject to study. However, studying algebra, calculus, and logarithms, among other subjects, makes economics more important.

The major objective of this research is to examine the trend of inflation, the trend of Nepal's economic development, trends of unemployment, and trends of remittances. Likewise, another one is the analysis and the effect of inflation on the GDP, unemployment, and the remittances of Nepal. The method of this research is to analyze and use the secondary data to create a simple regression model based on econometrics. Furthermore, the article concludes the mathematical relation between inflation and economic growth, inflation and unemployment, and inflation and remittances. There is a positive strong relationship between inflation among GDP remittances and unemployment.

This study analyzes the economic impact of the mutual tourism relationship between Nepal and India on the economies of both the countries. The main objective of this study is to study the exchange earning due to mutual tourism of both the countries and its effect on the economic development. Its method of study is to fit simple regression models for to analyze the trend of tourism of both the countries by using the use secondary data for this applying descriptive and analytical research design. In the discussion of this study, it is said that mutual tourism in Nepal and India as well as in the world community has helped to raise the country's foreign exchange earnings. Also, this study concludes that there is a positive relationship between tourist arrival and exchange earning. From this, tourism has made a great contribution to the economic development of both the countries. This is further confirmed by economic model R2 and P-value. The study demands more attention should paid for the development of tourism economy in both countries and tourism and travel facilities should improve to excess of tourism economy in Nepal and India.
