I took an assembly class a couple years back.  I can't stress enough how important it is to understand binary.  And that there are the 4 commonly referenced registers.  AX, BX, CX, DX.  And numerous other things.  (I've not done much in assembly beyond that class, but I found a few tutorials I thought were pretty good).

Here's some:
http://thsun1.jinr.ru/%7Ealvladim/man/asm.html (I think you should start here).

for addition simply

mov ax, < 16 bit number>
mov bx, < second 16 number >
add ax,bx  ; for addition
sub ax,bx, ;for subtraction
mul ax,bx  ; for multiplication
div ax,bx ; for division


for answers greater than 16 bit the result goes to DX register
