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
  • Hints
  • Chances

<math_problems>
  <problem id="01">
      <problem_level>0</problem_level>
      <num_chances>2</num_chances>
      <mathml>
          <? actual generated mathml here ?>
      </mathml>
  </problem>
</math_problems>

Goal Format

• Goal Mockup

Persistence of State Format

<state>
	<players>
	</players>

                               <required>
                               </required>
				<obtained>
				</obtained>
			</resource>
			<purchased_subgoal>

			<problems>
				<used>
				</used>
			</problems>
		</goal>
