The Arabic system of numerical notation is used in most parts of the world today. This system was first developed in India in the 3rd century BC. At that time the numerals 1, 4, and 6 were written in the same form as today.
The important innovation in the Arabic system was the use of positional notation, in which individual number symbols assume different values according to their position in the written numeral. Positional notation is made possible by the use of a symbol for zero. The symbol 0 makes it possible to differentiate between 11, 101, and 1,001 without the use of additional symbols, and all numbers can be expressed in terms of ten symbols, the numerals from 1 to 9 plus 0. Positional notation also greatly simplifies all forms of written numerical calculation.

Numerals are signs or symbols for graphic representation of numbers. The earliest forms of numerical notation were simply groups of straight lines, either vertical or horizontal, each line corresponding to the number 1. Such a system was inconvenient when dealing with large numbers.

Dynamo is a common device for converting mechanical energy into electric energy. This process depends on the fact that if an electrical conductor moves across a magnetic field, an electric current flows in the conductor.
Usually a dynamo includes an electromagnet, called the field magnet, between the poles of which a suitable conductor, usually in the form of a coil, called the armature, is rotated. The mechanical energy of the rotation, in the form of a current in the armature, is thus converted into electric energy.
