basically lets say you have 2.13 and a 5 over it. That means you have the decimal 5 spaces to the right, so it's 213000.00 if you have a -5 over the 2.13 you move the decimal 5 spaces to the left so it's .0000213 , however you won't learn the - till 8th grade I believe.


If there is no decimal then make one. If you have the number 2 and a 11 over it then you say 2.0 and move the decimal 11 spaces to the right 200000000000.0 then get rid of the decimal, so it's 200000000000.

Thats it it's very easy, you'll get it.
