Add two variables in assembly
<p>I have the next program in Assembler MASM,
I have a question about the sum records for Assembler MASM</p>

<pre><code> TITLE Suma variables
 INCLUDE Irvine32.inc
 .data
 a dword 10000h
 b dword 40000h
 valorFinal dword ?
.code
 main PROC
       mov eax,a ; empieza con 10000h
       add eax,b ; suma 40000h
       mov valorFinal,eax ; 
      call DumpRegs
      exit
 main ENDP
 END main
</code></pre>

<p>My question is when I use add with b, I'm adding only the value of the variable, or am I adding value and address in memory, because I understand that to get the particular value must be enclosed in [].</p>
