$srednia = (($sila + $defens) /2)

Math seems correct. I'm not aware of what your going for though. However I see that your using the same variable for your control and your read. This will result in incorrect results on any future read.

ie:

$sila = GUICtrlRead($sila)

This is saying take the data read from the control and set the variable of the control to the data. Now the control does not relate to a variable because it's been reset. Any time you read the control again it will be trying to read the data. (read the read the data ?!?)

ok i change this bad part of code to

Func _Result ()
    

$sila1 = GUICtrlRead($sila)
$defens1 = GUICtrlRead($defens)
$kukly1 = GUICtrlRead($kukly)



$srednia = (($sila1 + $defens1) /2)

$wynik = ($srednia / $kukly1)

Return $wynik
EndFunc

Now work greate but maybe is simple way to this ??
