Because there is an automatic conversion out of LEFT() that gives an string,
the + operation makes the conversion.

An easy way to have it working is involve the LEFT() with N() function
N(LEFT()), or doing an operation forcing the conversion LEFT()+0.

N 
Returns the numeric value of the given parameter. Returns 0 if parameter is
text or FALSE.
If an error occurs the function returns the error value.
Syntax
N(Value)
Value is the parameter to be converted into a number. N() returns the numeric
value if it can. It returns the logical values TRUE and FALSE as 1 and 0
respectively. It returns text as 0.
