Scientists use scientific notation because it is a convenient way of handling very large or very small numbers. Chemists, for example, use the idea of a mole, which is approximately 6.022 x 10^23 atoms or molecules of a substance. If we wrote this number out in traditional decimal notation, it would look like 602,200,000,000,000,000,000,000. Many of the constants used in physics and chemistry are also very large or very small numbers. For example, the Planck constant, important in describing the energies of quantized systems, is approximately 6.63 x 10^-34 Js. If we wrote out this number traditionally it would look like 0.000000000000000000000000000000000663.

Scientists use scientific notation to compute very large or very small numbers. Scientists deal in very large numbers and they need a shorthand way of writing them out as for example 999,000,000,000,000,000,000 = 9.99*10^20 in scientific notation.
Because sometimes numbers get really big or really small.
Because sometimes numbers get really big or really small.
It provides an easier way to write very large and very small numbers. APEX
Scientists use scientific notation to compute very large or very small numbers.
No. 35 is exponential notation, (3 is the base of the exponent 5), but in scientific notation the base must be 10 and the exponent must be an integer. 100.1 is exponential notation but not sci. notation.
Pharmaceuticals use scientific notation to compute very large or very small numbers.
Robotics engineers use scientific notation to compute very large or very small numbers.
There is no true opposite of scientific notation, but the closest answer is Standard Notation.
