Math Format

• Relatively Extensible
• Prototype Parser and Math Engine in PHP
• Polynomials only at this time
• Math engine is not yet complete, will have to discuss some ideas in meeting Tuesday
  • Ideas for storing expressions? i.e. log(x), (x^3), etc?
• Notes to self:
  • Operations?
  • Auto-generate constants?
• 'Barking up the wrong tree?' - MathML - http://www.w3.org/Math/
• Encapsulate MathML inside our own XML wrapper
  • Unique identifiers per problem
  • Level ID for each problem
  • Answer to problem

<math_problems>
  <problem>
      <lt sign="1">12</lt>
      <lt var="3">4</lt>
      16
  </problem>
  <problem>
      <lt>1</lt>
      <lt>4</lt>
  </problem>
</math_problems>

Goal Format

• Goal Mockup

Persistence of State Format

<state>
	<players>
	</players>
		<goal>
			<resource>
				<required>
				</required>
				<obtained>
