# Typesetting an integral

I am having trouble posting to the Calc forum for our first question. How do I type an Integral?

``````int_0^1 int_0^3 (-3x^2 + 6xy - 3y^2) dx dy.
Keep in that this doesn't include the double percent delimiters (`%%`) as described in this meta post, so you've got to include that, too.
