SSC EV H. Mathematics 1st Chapter Note. The subject of Higher Mathematics is applied worldwide in various researches of scientific innovation. Especially, the application of Higher Mathematics in Physics, Astronomy and space research is essential. Besides, Higher Mathematics is contributing meaningfully to various researches and experiments of everyday life. The learning of Higher Mathematics is very important to face the challenges of the scientific world of the 21st century, with all these things under consideration; the book titled higher mathematics has been introduced at the secondary level. In this case, sincere attempts have been taken to make the book easy and delightful, giving due emphasis to the understanding ability of the students.

## SSC EV H. Mathematics 1st Chapter Note

In the curriculum, national ideals, aims, objectives, and demands of the time have been properly reflected. It will ensure also the learning of the students according to their age, talent, and receptivity. In addition, a broad range starting from moral and human values of the students, awareness of history and culture, the Liberation War, arts-literature-heritage, nationalism, environment, religion-caste-creed, and gender is given due importance.

Everything is done in the curriculum to enable students to grow up a scientifically conscious nation to be able to apply science in every sphere of life and to realize the Vision of Digital Bangladesh 2021. All textbooks are written in light of this new curriculum. In the development of the textbooks, learners’ ability, inclination aptitude, and prior experience have been given due consideration.

Special attention has been paid to the flourishing of creative talents of the students and for selecting and presenting the topics of the textbooks. At the beginning of every chapter, learning outcomes are added to indicate what they might learn. Various activities, creative questions, and other tasks are included to make teaching-learning and assessment more creative and effective.

Algebra, (literally meaning “reunion of broken parts”) is one of the broad parts of mathematics, together with number theory, geometry, and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics. It includes everything from elementary equation solving to the study of abstractions such as groups, rings, and fields.

The more basic parts of algebra are called elementary algebra; the more abstract parts are called abstract algebra or modern algebra. Elementary algebra is generally considered to be essential for any study of mathematics, science, or engineering, as well as such applications as medicine and economics. Abstract algebra is a major area in advanced mathematics, studied primarily by professional mathematicians.

Elementary algebra differs from arithmetic in the use of abstractions, such as using letters to stand for numbers that are either unknown or allowed to take on many values.[4] For example, in {\displaystyle x+2=5} x+2=5 the letter {\displaystyle x} x is unknown, but the law of inverses can be used to discover its value: {\displaystyle x=3} x=3. In E = mc^{2}, the letters {\displaystyle E} E and {\displaystyle m} m are variables, and the letter {\displaystyle c} c is a constant, the speed of light in a vacuum. Algebra gives methods for writing formulas and solving equations that are much clearer and easier than the older method of writing everything out in words.

The word algebra is also used in certain specialized ways. A special kind of mathematical object in abstract algebra is called an “algebra”, and the word is used, for example, in the phrases linear algebra and algebraic topology.
