Alex,

Thanks for your reply. Here are some examples of equations in instructional text:


* Consider the implication [cid:image002.png at 01D7EC0B.D1B1E110] . Which of the above is the inverse?
* On a piece of paper, draw any triangle and label it ABC. Now, use a ruler to start a new triangle by drawing segment[cid:image004.png at 01D7EC0B.D1B1E110]that is longer than AB. Calculate [cid:image006.png at 01D7EC0B.D1B1E110] . Using a compass, at[cid:image008.png at 01D7EC0B.D1B1E110]construct an angle congruent to angle A. Extend the new segment to[cid:image010.png at 01D7EC0B.D1B1E110]so that [cid:image012.png at 01D7EC0B.D1B1E110] . Now, calculate [cid:image014.png at 01D7EC0B.D1B1E110] and [cid:image016.png at 01D7EC0B.D1B1E110] .
Theorem: If the scale factor of two similar figures is [cid:image018.png at 01D7EC0B.D1B1E110] , then the ratio of the perimeters is [cid:image018.png at 01D7EC0B.D1B1E110] , the ratio of the areas is [cid:image020.png at 01D7EC0B.D1B1E110] , and the ratio of the volumes is [cid:image022.png at 01D7EC0B.D1B1E110] .

Maybe a better way for me to summarize the problem is that we don’t know how to signify to the user that they need to switch from NVDA to MathPlayer for a portion of the sentence. Does that help identify the problem better?

Thank you,
