Is the answer 6K or 2K?
OK. Guys.
Say we have a Suction Temperature of 4c and a SST of -2c.
Mathematically the answer of 4 and -2 added together is 2
However 4 to -2 is a 6c split.
So which is the answer from a superheat perspective?

Grizzly, +4 and -2 =6. As in 0 to +4*c sensible heat, then add the -2 to 0*c as well as it is is also sensible heat.
To the optimist, the glass is half full. To the pessimist, the glass is half empty.

+4 -(-2)= +4+2 = +6

Either point crosses the 0 Datum hence it`s 6 k

Since superheat Is ^t of sst and st then it's 6C

Hey Grizzly
The superheat is 6.
I look at it this way - forget + and - numbers and work as if they are all 1 increments on a rule and count the difference between the two points.
Thats my story anyway.

OK. Guys "Hands Up"!
I already knew the answer, only I watched a chap calculating a superheat value recently and he took the negative value away from the positive.
When I pointed out the correct method (as everyone else on this post!).
I though "what a good topic for the forum"!
Sadly you are all to clever.
Some interesting way of explaining all the same.
Thanks Grizzly
