Forum:Synchro summon

Hi, I have some doubts about fusion/synchro summoning. 1) Fusion summon is a special summon? So can I normal summon a monster and also fusion summon another one? (I think I can special summon in 1 turn as many monster as I can, isn't it?) 2) Synchro summon is like fusion summon, and for fusion summon I can send to the graveyard monster from the field or my hand. Can I do the same for synchro summoning or only from the field? Thx.
