Why would you count a compound expression, with internal spaces, as one word?
Why would you count a compound expression, with internal spaces, as one word?
The spaces are mere typesetting. n^2+2 is the same expression typeset a different way.
Technically "n^2+1" has no spaces.
And I guess one way to think about it is that terms in an expression can be viewed as letters, so the expression then becomes a word.
