Scientific notation is a way of writing that is often used in physics and chemistry when very large or very small numbers are being
manipulated. The scientific notation of a number is a digit that is between 1 and 9,
possibly a number with point, then a times sign, then a power of 10.
Scientific notation is useful when we need to write very large numbers. For example to write down the weight of the Earth, we do not write m=6400000000000000000000000 kg, but rather m= kg.
