Negative numbers to positive

I need to convert the negative numbers to positive like this: -1356  to (1356) and the positive numbers should become empty cells with a –   See attachment for an example. (always good to make something negative positive :))

Hi @Taoufiq_Zarra   thanks.

My expression currently looks like this:

((1-Sum([Sum of Total Sum of Hours [ITM]]])/Sum([Count of EQ ID])/3.1)*Sum([Sum of Total Sum of Cost [ITM]]]))*-1

With the *-1   I made the negatives positive. 

How do I need to integrate your code in this?

With @Taoufiq_Zarra  solution.

If(((1-Sum([Sum of Total Sum of Hours [ITM]]])/Sum([Count of EQ ID])/3.1)*Sum([Sum of Total Sum of Cost [ITM]]]))<0,
-((1-Sum([Sum of Total Sum of Hours [ITM]]])/Sum([Count of EQ ID])/3.1)*Sum([Sum of Total Sum of Cost [ITM]]]))
)
