> How do I fix the LaTeX?

When you write too long formulae in a single line, then they are not appropriately displayed. In order to avoid such an overhul, you need to separate formulae. For example, {x+y,φxy|conditions} can be expressed as {x+y|conditions} ∪ {φxy|conditions}, and then you can make a new line arround ∪ by inserting "\\".

You can copy the source cord below: \begin{eqnarray*} X & = & italic \ \textrm{roman} \\ & & \cup {\bf bold} \cap \mathbb{N} \end{eqnarray*}
