1) Move the decimal until your number appears to be between 1 and 10 count the spaces that you move the decimal.

2) use the number of spaces as the exponent of 10 (the base)

3) if the original number was greater than 10, the exponent is positive, if the original number was less than 1 then the exponent is negative.

EX: 250,000 becomes 2.5 x 105

but 0.0025 becomes 2.5 x 10-3

Scientific Notation

Sometimes. Scientific notation is used to express very small or very large numbers. If the problem does not involve any such numbers then there is no need for scientific notation.

Write the mantissa as a negative number.

Scientific notation is often used to represent very large and very small numbers. Actually, you can also express a "normal-sized" number in scientific notation. So, whenever there is a number, you may use scientific notation.

Scientific notation lets us express a large or a small number without having to write a lot of zeros before or after it. Try writing out 3 x 10^9000 without scientific notation.

- when adding or subtracting in scientific notation, you must express the numbers as the same power of 10. This will often involve changing the decimal place of the coefficient.

Scientific notation is a way to express very large (or very small) numbers. You would represent 1,000,000,000,000,000,000,000 as 1*1021.

No. Scientific numbers are constants that appear in science. They may or may not require scientific notation.

Scientists have developed a shorter method to express very large numbers. This method is called scientific notation. Scientific Notation is based on powers of the base number 10.The number 123,000,000,000 in scientific notation is written as :

You do not have to deal with a very large number of zeros.

yes...it helps show both very small and large amounts.

Scientific notation is useful to represent numbers which are very large or very small.

Scientific notation is a way of writing numbers that are too big or too small to be conveniently written in decimal form. In normalized scientific notation all numbers are written in the form a x 10^b (a times ten raised to the power of b) where a is a nonzero single-digit integer and b is an integer.
