Calculate the positive or negative net

[GigaFluxx]

So I have a file that is looking at product coming in through a shipment.
I have one field that shows the number of units shipped and another field that shows the number of units received.
In a third column I would like it to tell me if between those number it is positive or negative net via a formula.

Example

Units shipped	Units received	Quantity Delta
0	1	+1
1	0	-1

I know it's probably simple and I'm just not thinking of it but if someone could help me with a formula, I'd appreciate it.

With A1 is shiped, B1 is received, C1 = B1-A1

Wow, that was simple. What a brain fart.

Thank you!
