What do these numbers mean?

What do these numbers mean, it seems a bit weird for ft/m.

(sorry for exposing some of your callsigns)

It shows the difference in altitude between you and the other aircraft.

now it makes more sense, thanks

That’s the altitude separation from you. Here’s a neat little table to understand it a bit

Altitude	Altitude Difference in 1000s,	Altitude Difference in 100s	Altitude Difference in 10s.
+ = They are above you	1 = One thousand Feet Above	1 = One Hundred Feet above	1 = 10 Feet Above
- = They are below you	1 = One thousand Feet Below	1 = One Hundred Feet Below	1 = 10 Feet Below

Hope this helps!
