Adding double and triple integrals
$begingroup$
As I know, we can easily add single integrals as follows: $$int_a^bfdx + int_b^cfdx = int_a^cfdx $$
However, I'm not sure how this works for double and triple integrals? For example, suppose I have a discontinuous volume that I want to find with the following bounds:
- z: $x^2 to 3-y$
- x: $-sqrt3 to -1$ and $1 to sqrt3$
- y: $0 to 2$
Can I write this as the triple integral:
$$int_0^2 int_{-sqrt3}^{-1} int_{x^2}^{3-y} f dzdxdy + int_0^2 int_{1}^{sqrt3} int_{x^2}^{3-y} f dzdxdy $$

You surely can. Integrals over disjoint regions add up.
