Bulding a hack and got some issue with pointers

I'm Building a hack with VB and I have some pointers problem
How do i make the pointer show me the address?
the pointer is 008axxxx[cant say] and the hex that comes with it is 54
the value that the pointer retained me once was 313919512
how do i get to the address from that?
and no, i dont want to use CE

313919512 = 12B60818 in hex is the address the pointer is pointing to.
12B60818 + 54 (hex too) is the address of the value you want to modify.

this address will always be a different one since it's dynamic.

how can i sum to hex values? is it that possible? 12B60818 + 54
