1. Move the decimal to the right of the first number that isn't 0. EX: .00345 -> 3.45 2. Count the number of spaces you moved the decimal. The decimal for my example is moved three times. ((.00345 -> 0.0345 -> 00.345 -> 003.45)) Because I moved the decimal to the right, the notation will be negative. *If you ever need to move the decimal to the left, the notation will be positive. 3. Set the new number(3.45 in my example) times 10 to the X power, where X is equal to the number of times you moved the decimal. So, the final answer for my example is 3.45 x 10-3. Hope this helps you solve your problem.
