Mathematics is an essential and fascinating branch of human knowledge. It has important uses in many areas of modern life, including science, industry, and business.
Mathematics can be definedsimply as the study of quantities and relations. It uses numbers and symbols to do this. This definition, however, does not explain that mathematics can be divided into many different branches. Thereare at least eight, areas of math generally studied by elementary, secondary, and college students: arithmetic, algebra, geometry, trigonometry, analytic geometry, calculus probability andstatistics.
Arithmetic can be divided into four basic operations: addition, subtraction, multiplication, and division. It is the simplest branch of math and is usually studied in school. After arithmetic,students usually study algebra. Algebra is more general them arithmetic. It uses letters such as "x" and "y" to find unknown numbers. One interesting invention of algebra is logarithms. They are usuallyfound by referring to a logarithm table.
Geometry is generally learned in secondary school. This branch of math deals with lines, angles, planes, and solids. For purposes of teaching, geometry is oftendivided into two branches. Plane geometry deals with shapes, such as circles and squares that lie on a flat surface. Such shapes are in two dimensions. Solid geometry deals with shapes that have threedimensions. Such shapes are spheres, cubes, and pyramids.
The branch of math that deals with the relation between the sides and angles of triangles is trigonometry. Trigonometry also is often dividedinto two branches: plane trigonometry deals with triangles on a flat surface. Spherical trigonometry deals with triangles on the surface of a sphere. Trigonometry is very useful to navigators,astronomers, and surveyors.
Analytic geometry is the branch of math that applies algebra to geometry.
Engineers and physicists often used it. An example of analytic geometry is the drawing of a curved...
