Exponents and Scientific Notation

First I am going to tell you about exponents. They are tricky at first, but you will get it in a little. For a example lets say you have the number 32. The three is the base number because that is the main number that you will be multiplying with. The 2 is the exponent that shows how many times the base number multiplies. The answer for 3would be 9 because 3x3=9.
Next there is scientific notation. Say you have the number 520,000. First the easy part is you put down 52 because those are the only numbers besides 0. Then you count how many 0's there are. In 520,000 you would put down 52 and the since there are  4 0's you would put down 524x10 and thats your answer.

Good job - One note about scientific notation - The decimal always goes after the first number and you count how many places you needed to move the decimal to get it there. For example 62,000 becomes 6.2 x 10 to the 4th power.
