DAX Formula for subtracting columns?

I am trying to caluculate current year revenue(column C) by subtracting prior revenue (column B) from revenue to date (column A).  In theory, the formula would be A - B = C.  Would I use some form of SUM formula to subtract these?  I'm new to Power BI and need help, please!  I've worked on this several hours, with little success.  All suggestions are welcome!

Try with:

 

C=Calculate (Sum(Table[A]))-Calculate (Sum(Table[B]))

Hi alhyde,

 

What is your current situation?

The formula provided by Vvelarde should have the same results with the formula below:

C = A - B

 

Adding a blog for reference:

If that formula didn't meet your requirements, then please post back.

C=Calculate (Sum(Table[A]))-Calculate (Sum(Table[B]))

What if one of these tables is a measure?

 

Can you do C = A - B if B is [B]?

@Vvelarde thanks for the solution!  It worked!
