Quick MathSpeak Tutorial
Without Semantic Interpretation, MathSpeak speaks the symbols as they appear and cannot deduce their meaning. For example, the crosssign can be either crossmultiplication or crossproduct, so MathSpeak will just say "cross." Since it is sometimes ambigious whether a comma is a delimiter or a comma within a number, numbers are spelled out except for the highest level of Semantic Interpretation.
For most fractions, the beginning is indicated with "start fraction", the horizontal line is indicated with "over", and the end of the fraction is indicated by "end fraction". For the semantic interpretation, most numeric fractions are spoken as they are in natural speech. Also if a number is followed by a numeric fraction, the word "and" is spoken in between.
Example 3

StartFraction
x Over
y EndFraction
plus a equals StartFraction
x plus a y Over
y EndFraction

Example 4

a plus StartFraction
b Over
c plus d EndFraction
notequals StartFraction
a plus b Over
c EndFraction
plus d 
Notice that the following numeric fraction is not spoken as "twentyfifths," since this could be confused with the ordinal value of 25.
Fractions that contain other fractions are spoken differently than simple fractions, the beginning of the indicators are repeated to indicate the number of levels of nested fractions.

"Raised to the power of" is indicated by the term "superscript"  implying that the term following has the level of "raised power." "Supersuperscript" implies that there are two levels of superscripts in sequence. A superscript level will continue until a different level is stated. If the expression continues at the original base level, the term baseline is stated.

Square roots are stated with "start root" at the beginning and "end root" at the end.
