This is just a matter of coding style. It may reflect variation in 
writing mathematical expressions: A fairly common practice is to divide 
before an operator in display formulas, but after an operator in text 
formulas.

A “+” sign at the end of a line normally indicates that the expression 
continues on the next line, whereas a “+” sign at the start of a line 
normally indicates that the expression is continuation of something that 
started on the preceding line. In mathematics, people may use “+” both 
at the end of a line and at the start of the next line, for assumed 
clarity, but this is nonstandard and cannot of course be used in 
programming, as it would cause a syntax error. So you have to make your 
choice.
