Firstly there are two rules that you should know
(1) oxidation of an element = 0

(2) the O number of a monoatomic (one atom) ion is the same as charge on the ion


Now... take H2SO4

let oxidation state of S be X (there is only 1 X)

Oxidation state of    (Hydrogen) H2 =+2  AND (oxygen)  O= -2 (But there are in fact 4 O.... so it will become (- 2)*(4) = -8

so (+2) + (X) + (-8) =0 .................... X = +6


hope it was helpful :)
