You can create custom Python-evaluated input problems that provide
partial credit or that randomize variables in the Python code. You can

In math expression input problems, learners enter text that represents a
mathematical expression into a field, and text is converted to a symbolic
expression that appears below that field. You can refer learners to
<a href="http://edx.readthedocs.io/projects/edx-guide-for-students/en/latest/completing_assignments/SFD_mathformatting.html" target="_blank">

</p>
<p>
Math expression problems can include unknown variables and relatively
complicated symbolic expressions. The grader uses a numerical sampling to
determine whether the student’s response matches your math expression, to a
specified numerical tolerance. You must specify the allowed variables in the
expression as well as the range of values for each variable.
</p>
<p>
To create these problems, you use MathJax to change your plain text into

In these problems (also called custom JavaScript problems or JS Input
problems), you add a problem or tool that uses JavaScript in Studio.
Studio embeds the problem in an IFrame so that your students can
interact with it in the LMS. You can grade your students' work using
JavaScript and some basic Python, and the grading is integrated into the
edX grading system.
</p>
<p>
The JS Input problem that you create must use HTML, JavaScript, and
cascading style sheets (CSS). You can use any application creation tool,
such as the Google Web Toolkit (GWT), to create your JS Input problem.
