There are positive indices and negative indices
Example:
? —> negative indices —>
Method
instead of increasing the number in will decrease it. The negative symbol will become
So the negative symbol disappeared from the number therefore it become 
?
we put the 5^2 as the denomitor and 1 as the numerator
it will become this:
?
=0.04
? —> positive indices = 
?
Positive indices is less confusing since we only increase the number
