Win32 Application - Help With Math

Hello, I'm currently working on a *** Game Predictor. I thought it was a pretty cool idea for a beginner.... Anyways, I'm kind of a noob and would really appreciate it if somebody can help me out with the math part of the code.

Code:

---

#define _WIN32_WINNT  0x0500
#include <windows.h>
#include <Wincon.h>
#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
    //Data Table
    int iTeam1apy;
    int iTeam2apy;
    int iTeam1ary;
    int iTeam2ary;
    int iTeam1aya;
    int iTeam2aya;
    double dTeam1as;
    double dTeam2as;
    double dTeam1ai;
    double dTeam2ai;

    int iTeam2wl;
    double dTeam1line;
    double dTeam2line;
    double dTeam1 = 10.0; // Home Team Gets 10.0 Points Advantage
    double dTeam2;
    double dTeam1p;
    double dteam2p;
    double dTotal;
   
    //Full Screen Mode   
    HWND hWnd = GetConsoleWindow();
    ShowWindow(hWnd,SW_SHOWMAXIMIZED);

    system("title *** Game Predictor BETA Handicapping Software");
    system("color E2");

    //
    // Sport Book odds : If dTeam1line < dTeam2line then dTeam1 + 10.0 Points
    //                  If dTeam2line < dTeam1line then dTeam1 - 10.0 Points
    //
    // Comparing The Teams: If dTeam1 > dTeam2 then dTeam1 Wins
    //                      If dTeam2 > dTeam1 then dTeam2 Wins

PS: I don't know if this is making any sence to you gurus, I'm a noob.. :S
Thanks Very Much.

well, you have all the numbers, and you spelt out all of the maths, so just code it up.
