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> <answer>3</answer> </problem> </math_problems>
