Computation for pascal's triangle values by calculating along the row so I don't lose it in the future. This is susceptible to round-off errors because we multiply before a divide when the triangle gets very large.

PascalsMath.cpp

// Assumes row/col are 1 indexed
int PascalsMath(int row, int col)
{
    // Enable mirroring about the central pivot of the row
    col = min(col, row - col + 1);

    int value = 1;
    int numerator = row - 1;
    int denominator = 1;
    
    while (--col > 0)
    {
        value = (value * numerator--) / denominator++;
    }
    return value;
}
