### EVs and IVs are really important.

*EVs*

To explain EVs simply, for every 4 EVs in a stat you gain 1 point in that stat. The maximum amount of EVs you can have in a stat is 252. You can max out 2 stats and put the remaining 4 in another one.

So in total you have 508 useful EVs available(you actually have 510 but the last 2 don't make a difference).

*IVs*

IVs are a bit more complicated. They are like Pokemon *genes*. They determine your Pokemon's stats and **cannot be changed** unlike EVs.

HP IVs are calculated differently from the rest. These two formulas are used to calculate the IVs:

Aside from determining stats, they also determine what kind of hidden power your Pokemon will have.

>The last binary digit for each stat sets the move's Type, and the second-to-last digit sets the move's Power.
