How do I interpret this delta expression?

I'm trying to understand the following equation:

I know that is delta and that it implies a difference between something. My current guess is that y is the delta between x and a * b, but my knowledge is limited so it's just a guess.

I know [] sometimes can be used instead of (), but if I was to interpret [] as () in this example, that would translate to: y = * ∗

I'd be very happy if someone could help me interpret the equation.

Best regards!

Edit: The full equation is as follows:

CL_δ = (_+_)/ ∗ [_ ∗ _]

CL_δ is the coefficient of lift due to elevator deflection. (aerodynamics)

Could you give some context in which this specific equation occured? – Janik Aug 29 '16 at 11:40
where did you get the expression from? – Josu Etxezarreta Martinez Aug 29 '16 at 11:40

The symbols $\delta$, $[\phantom{r}]$, and $*$ all are used differently in different contexts. – GFauxPas Aug 29 '16 at 11:42

@johnor999 You should add that equation to the body of your question. – GFauxPas Aug 29 '16 at 11:52

$\delta_e$ is the deflection of the elevator angle. – Mauro ALLEGRANZA Aug 29 '16 at 12:01
I think that this quantity is multiplied by $[ \ldots ]$ and that there is nothing misterious in the use of square brackets. See here. – Mauro ALLEGRANZA Aug 29 '16 at 12:02
Yes δ is the deflection angle, but why use [ ]? – johnor999 Aug 29 '16 at 12:06
