[AccessD] A2K: I've forgotten the syntax to convert negatives to positives

Hello all

I have a couple of numbers that are negatives.
I wanna sum 'em then turn 'em the result into a positive eg -1 + -1 = -2
I wanna show the answer as 2

I got an answer of this list before - can't rememeber or find the response
It was something simple like clng(blah)

many thanks in advance

DD
