Hello!
In our case, loss will mean -, and gain will mean a whole number. You do not need to put a +. Just put it as a whole number.
Loss of 3=-3
Loss of 8=-8
Gain of 4=4
Gain of 23=23
Loss of 6=6
The only thing you need to do is take away the plus marks. However, this will not give you an incorrect answer, it is just standard to write it normal. Aside from that, you are correct!
I hope this helps!
