Naming alkenes

Do we need to put a number to indicate the double bond? (and triple in alkynes)

Yes, when the alkene carbon chain has four or more carbon atoms then the position of the double bond needs to be given in the name.

It can also be included before the ene part of the name.

So for 3,6-dimethyl-3-octone where 3 is the the number of the carbon the double bond starts at you can also write it as 3,6-dimethyloct-3-ene.
