All together vs. Altogether
No. "All together" is used to refer to a collection of people or things that are in the same place; for example, "The spoons are all together in the left drawer." "Altogether" means "in sum" or "in total"; for example, "Altogether, the repairs to my car cost $4000."
"All together" means everyone or everything together. Where "altogether" is an adverb and means "all in all," "all told," or "completely."
Examples:
It's time to sing. All together now!
That was altogether too difficult.
