Scientific notation is a way of writing numbers that are very large or very small. It is expressed as a number between 1 and 10 multiplied by a power of 10.
Scientists use scientific notation to make very large or very small numbers easier to work with. It also helps to reduce the number of zeros and makes calculations more efficient.
To convert a number to scientific notation, move the decimal point so that there is only one non-zero digit to the left of the decimal. Then, count the number of places the decimal point moved and use that as the exponent of 10.
To calculate with numbers in scientific notation, first convert all numbers to the same power of 10. Then, perform the desired operation on the coefficients and add or subtract the exponents.
The benefit of using scientific notation is its ability to easily represent extremely large or small numbers without having to write out numerous zeros. It also allows for more precise calculations and easier comparison of numbers in different orders of magnitude.
