No, the reason this fails is because you are trying to multiply text 
by a number.  If this worked, the original problem would not exist: 
the user would be able to involve his text values in mathematical 
formulae directly.  And it's wrong to think of that leading single 
quotation mark as actually being in the cell.  Preceding a numeric 
value by a quotation mark is how you indicate in typing that you want 
the value to remain as text and that you do not want the value 
interpreted as a number.  It's also the way that values shown in the 
Input Line that might appear to be numbers are indicated actually to 
be text.  But there is no quote in the cell.

Indeed: it won't find it because it's not there!

Aaargh!  The quotation mark is not added to the cell, but is used to 
indicate that you have preserved the value as text, not had it 
interpreted as a number.  That's most definitely a feature, not a 
bug!  There are genuine uses for this: if you live in Newark, New 
Jersey, USA, your ZIP code may be the five-character text string 
07102.  But the postal system will not like your misrepresenting this 
as 7102 - the number seven thousand, one hundred and two.
