I've been told that the article for 'same' is always 'the', but sometimes I think it feels right to say 'in a same way' when I have not yet but am going to talk about the way or when I won't talk about it at all because that is not important.
For example, I just said (at another place)
A and B are used in the same way, A+ and B+.
but could I say it with 'a' instead of 'the'?
A and B are used in a same way, A+ and B+.
