To convert from scientific notation to a normal number:
move the decimal as many places as the power of 10

...to the left
if it's a negative power

Meaning you have
a small number.
...to the right
if it's a positive power

Meaning you have
a big number.

Example 1:
Change 1.753 x 108 into a normal number

1.753 x 108     1753_ _ _ _ _    = 175,300,000
                       
                     
power of 8
8 spaces
Fill 5 blank spaces
with zeroes.
positive 8, meaning big #
to the right
Example 2: Change 8.05 x 10-3 into a normal number

8.05 x 10-3     _ _ 805   = .00805
    
                  
 
   
power of 3
3 spaces
Fill 2 blank spaces
with zeroes.
negative 3, meaning
small #
to the left


Rather than memorize whether to move left or right it's easier to remember that, with scientific notation:
negative powers of 10 go with small numbers (less than 1),
and
positive powers of 10 go with large numbers (greater than 1)

Example 1: Change 950,000 into scientific notation
positive powers of 10 go with large numbers (greater than 1)
Example 2: Change 7 x 10-6 into a normal number


negative powers of 10 go with small numbers (less than 1)

As many of you know, Winpossible's online courses use a unique teaching method where an instructor explains the concepts in any given area to you in his/her own voice and handwriting, just like you see your teacher explain things to you on a blackboard in your classroom. All our courses include teacher's instruction, practice questions as well as end-of-lesson quizzes for practice. You can enroll in any of our online courses by clicking here.

The format of Winpossible's online courses is also very suitable for teachers who are using an interactive whiteboard such as Smartboard on Promethean in their classrooms, because the course lessons can be easily displayed on such interactive whiteboards. Volume pricing is available for schools interested in our online courses. For more information, please contact us at educators@winpossible.com.
