Hopefully, correct me if I'm wrong, the following answers your question:

set a to 2
=2, the object 2 is given the name a, a points to the object 2

set b to a
=2, the object 2 is given the name b, , b points to the object 2

set c to a + b
2+2=4, the object 4 is given the name c , c points to the object 4

c

2+1=3 , the object 3 is given the name a , a NOW points to the object 3 and
no longer the object 2, b STILL points to the object 2
>
set c to a + b
3+2=5, the object 5 is given the name c , c NOW points to the object 5 and
no longer to the object 4

c
