 Sometimes a mathematical expression consists of multiple mathematical expressions, and they all appear on the same line. Examples are functions where the domain is a restricted interval, or a differential equation, with an intial value. In such cases, all the expressions should be captured in the same `<math>` element separated by `<mspace>`. Here is an example:
