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, scientific notation, and scientific notation are examples of scientific notation

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= scientific notation of the Earth Masskg.
