NH4 is (+1) (Oxidation number of N in NH4+ is -3 Oxidation number of each H in NH4+ is +1)
Ce is +3
SO4 is -2 ( Oxidation number of S is +6 and O is -2 in SO4)
You have 2 polyatomic ions in this. NH4 and SO4
NH4 is +1 (you will probably have to memorize common ions and this is very common.) Since NH4 is +1 you can look at each element individually. H is in group 1 (look across the periodic table. There are 8 long columns. Elements in group 1 tend to lose an electron. That makes them a positive number since they will have more protons than electrons. That would mean H is +1. N is in group 5. It usually is going to either lose 5 or gain 3. (All want 8 except for H and He that want 2). N must be negative to balance out the ion. Since H is +1 and you can see in NH4 that there are 4H's that means you have +4 for all the H in the ion. The ion totally is +1. 4 - 1= 3 So N gains electrons and is -3. 
SO4 is a poly atomic ion that is -2. O and S are both in group 6. That means they want to lose 6 or gain 6. O is going
