In the video lesson, you will learn how to convert a number from standard notation to scientific notation by moving the decimal place. By doing this really big numbers and really small numbers can be easily described.
e.g to write 470,000 in scientific notation, write the number 4.7, (so that there is only one digit to the left of the decimal point), then count the number of places that the decimal point must be moved to get back to 470000 ( in this case is 5). If the number is big it is a positive exponent (like this one - which we'd write as 4.7 x 10^5).
A little number - like 0.0000033 gives a negative exponent (in this case 3.3 x 10^-6).
