calculation — Used to delimit a MathML v2 calculation
The calculation element wraps around MathML 2 content markup describing how the signal is calculated. The calculation may include both constants and variables; other variables are included by using their varID string in a MathML content identifier (ci) element. The calculation element must have one and only one subelement, and the subelement must be a 'math' element containing 'content' markup.
