An easy method of writing a very large or small number. A
scientific notation is a decimal number between 1 and 10 multiplied
by the power of 10. For example, 987,000,000 could be written
in scientific notation as 9.87 * 108, 9.87 * 10^8, or
9.87+E8
To convert a real number into a scientific notation, follow the
below steps.
- Place a decimal point after the first digit.
If we were using the same number we used above, the decimal point would
be placed after the nine.
- Complete the remainder of the number excluding the trailing
0's. So our number would be 9.87, this number is also known as
the coefficient.
- To find the exponent, count all the digits up to the decimal point.
Because our number was nine digits long, this would mean we have
an exponent of eight.
To convert a scientific notation into a
real number, follow the below steps.
- Assuming our scientific notation was 8.01+E5.
- Calculate 8.01 * 10 * 10 * 10 * 10 * 10
- The answer for this scientific notation should be 801000.
