Concept introduction:

The measurement is a characteristic number to the object that can be compared with other objects. The scope of the measurement depends upon the context and event. Measurement is commonly used as an international system of unit as a comparison framework. The system has 7 fundamental units like kilogram, meter, candela, ampere, kelvin and mole. The metric system is a decimal system used to measure the length, meter, the mass, the kilogram. The metric system is a single basic unit used for number of physical quantities. The quantities are derived from the SI units. For this scientific notation is most important.

Scientific notation is the way to express the numbers that are too big or small that can be written conveniently in the decimal form. It is commonly used by the scientist, mathematics, to simplify the certain arithmetic operation. In the scientific notation, the numbers are indicated by

M $\times$ 10ⁿ
