What does the "$\cdot$" mean in an equation I am trying to solve an equation for a project that I am undertaking. The equation is very long and its probably not necessary to show it all here. Most of the equation is fairly straightforward; i.e., $1+(\frac{w}{W})(\frac{d}{t})$, etc. but at the very end it reads $\left(1+\frac{w}{W}\right)\left(\frac{D}{T}\right) \cdot \frac{1}{T}$.      
$w$, $W$, $D$, and $T$ are all either constants or variables that I have solved already.
My question is, what is the "$\cdot$" symbol asking me to do?
In the equation in the book, the "$\cdot$" is in the centre of the dividing line between $1$ and $T$, as opposed to down low like a period or full stop.
I appreciate that I have phrased this question in an awkward manner, but as is obvious, I am no maths expert.
Here is a photo of the equation in the book:


Like this?
$$ \left(1+\frac{w}{W}\right)\left(\frac DT\right)\cdot\frac1T $$
That means multiply.
