Working with points of a plot?

Is there any way to work with multiple points of a plot?

for example,

if I had 2 points

A= (-2, 3); B = (5, 3);

can I do basic operations like add and multiply of these 4 numbers -2, 3, 5, 3 to get a new plot point say, C = (3, 3)?

like, how do I get (3, 3) or something

A=[-2, 3];
B =[5, 3];
C=A+B
D=A.*B
