Is this how a recursive would work?  I think I am missing something.  I think I need two registers, but I don't know how to make it work.  Here is what I have
``        ;N is in eax            math:             push        eax                 ;save callers ebx            cmp         eax,1               ;compare eax to 1            ja          non_base            ;if above 1 jump to non_base           base:            mov         eax,1               ;move 1 into eax            pop         ebx                 ;return callers ebx                       retnon_base:            push        eax                 ;save callers eax            sub         eax,1               ;subtract 1 from eax                        call        math                ;call math                        ret``

doesnt fibonacci go up? 1 1 2 3 5 8 11 and so on?, so why the dec eax?

well it is f(n)=(n-1)+(n-2) or that is the equation I am suppose to work with.

Better look again at the Fibonacci equation.

It's

F(n) = F(n-1) + F(n-2)

n, n-1, and n-2 aren't used in the equations as values. They are counters that indicate where in the sequence a specific Fibonacci number appears.

Ok, then I am completely confused...I have read over it a number of times, I just don't understand.

``mov ecx, 10    ; loop countmov eax, 1      ; first valuemov ebx, 1      ; second valueloopie:; print value in eax, its the number (i didn't put this code in as i'm sure you can do it yourself for your homework)lea edx,  ; number = first + secondmov eax, ebxmov ebx, edxloop loopie``

that code generates the sequence...
1 1 2 3 5 8 13 21 34 55 89 144

it can do more by adjusting ecx to a higher value

fibonacci sequence works by adding first and second to make new value, and working from that...

1 1 is the initial starting value...

1+1 = 2
1+2 = 3
2+3 = 5
3+5 = 8

and so on..
