syntax highlighting bug in Structured Data part

[acud]

In the tip section within Function sets:

A function set of form [A -> B] will have 
 elements in it. If there were two tasks and three CPUs, that would be :math`(2^3)^2 = 64` possible functions.

Here, :math should be changed to whatever should yield the right result or simply be removed in favor of the usual syntax highlighting

Should be :math:, not :math
