Why is var m = 6 + + + + + + + + 6; valid in c#?

Question

Title is most of the question, what allows this to be valid code? Is there any benefit or trick that would allow me to utilize this?

Answer 1

The unary plus operator has higher precedence than the addition operator, just split your expression into multiple grouped expressions and it will seem pretty obvious:

var m = 6 + ( +( +( +( +( +( +( +( 6 ))))))));
      //6 + 6
