\int \int x^{3} d x d x

\int x^{3} d x = \frac{x ^{4}}{4} + C

= \int (\frac{x ^{4}}{4} + C) d x

\int (\frac{x ^{4}}{4} + C) d x = \frac{x ^{5}}{20} + C x + C

= \frac{x ^{5}}{20} + C x + C

\int \int x^{2} + y d x d y

\int_{1}^{3} \int_{2}^{4} e^{x^{2} + y^{2}} d y d x

\int_{0}^{\infty} \int_{0}^{y} c e^{- x - y} d x d y

\int \int x^{y} d x d y
