This e-book describes what vectors are and how to add, subtract and multiply them by scalars.. The article provides a summary of the elementary ideas about vectors usually met in high school mathematics. The follow-up article 'Multiplication of Vectors' discusses scalar products and vector products. Vectors are an absolutely essential 'tool' in physics and a very important part of mathematics. Vectors are important in navigation where the actual velocity of an aeroplane relative to the earth is

The surface area of a solid object is a measure of the total area that the surface of an object occupies. This e-book details how to find the surface area of rectangular, triangular and cylindrical prisms. In geometry, a rectangular prism has 2 ends and 4 sides. Opposite sides have the same area. The surface area is the sum of the areas of all six sides. On the other hand, a triangular prism is a three-sided prism; it is a polyhedron made of a triangular base, a translated copy, and 3 faces joi
