Dimensions using literals and variables

GIZMOGIZMO Member Posts: 11
Specifying literal numbers in a dimension equation also using variables generates an error:

(((5-(#Pipe2halfs40OD/2))/2)+(#Pipe2halfs40OD/2))   <===== Invalid expression error

Changing the literal number "5" followed by a minus sign into a variable with the value of "5" is considered a valid expression, and gets the right answer = 3.219

(((#Five-(#Pipe2halfs40OD/2))/2)+(#Pipe2halfs40OD/2))

where #Pipe2halfs40OD = 2.875 and #Five = 5

ie, it accepts a literal number associated with a divide "/" (and I assume multiplication "*"),
but not with simple subtraction "-" (and I assume addition "+").
