 As mentioned, the computation is split into four parts. Part one is the
 simple tensor calculation of :math:`|2x|`, which can be traced. Part two
 is the iterative product calculation that represents a data dependent
 control flow to be scripted (the number of loop iteration depends on the
 input at runtime). Part three is a trace-able
-:math:`\lfloor \sqrt{a/5} \rfloor` calculation. Finally, part 4 handles
+:math:`\lfloor \sqrt{a/5} \\rfloor` calculation. Finally, part 4 handles
 the output cases depending on the value of :math:`z(x)` and must be
 scripted due to the data dependency. Now, let's see how this looks in
 code.
