We defined an operation denoted by $*$ on the integers, which satisfies the following conditions: 

1) $x * 0 = x$ for every integer $x$;
2) $0 * y = -y$ for every integer $y$;
3) $((x+1) * y) + (x * (y+1)) = 3(x * y) - x y + 2 y$ for every integer $x$ and $y$.

Determine the result of the operation $19 * 90$.
