Also, too and as well
I also hope so
I hope so too
I hope (so) as well
Is the meaning of these three senteces the same? Are they correct? Is there a different usage? Such as one is used more talking or writing?
Hope you are having a nice day!
Thank you!

Answer

"I also hope so" and "I hope so too" are both correct, and acceptable in written or spoken language.  The meaning is the same for both.

To me, "I hope so as well" does not really sound natural.
