 Sci Advisor HW Helper P: 2,004 If you use \ limits_{down}^{up} you can get the text 'down' and 'up' above and below the integral signs. Also works for summation symbols. $$\iiint \limits_{x \geq 3, y \geq 4, z \geq 5, 2z - x \geq 5} f(x, y, z)\, dx\,dy\,dz$$ But it still looks crappy. I'd advice just writing $$\iiint \limits_{R} f(x, y, z)\, dx\,dy\,dz$$ where $$R=\{(x,y,z)|x \geq 3, y \geq 4, z \geq 5, 2z - x \geq 5\}$$
