Test - editing using the Rich Content Editor via a LTI tool

Some text.

$\begin{pmatrix}t^{\prime} + z^{\prime} & x^{\prime} - iy^{\prime} \cr x^{\prime} + iy^{\prime} & t^{\prime} - z^{\prime}\end{pmatrix} = \begin{pmatrix}\alpha & \beta \cr \gamma & \delta\end{pmatrix} \begin{pmatrix}t + z & x - iy \cr x + iy & t - z\end{pmatrix} \begin{pmatrix}\alpha^{*} & \gamma^{*} \cr \beta^{*} & \delta^{*} \end{pmatrix}$

This is a second test. Which contains two sentences.

I added a new sentence on 2016.07.19. To create a new Test 3 page.

If I selected the equation above and then invoke my editor button it passes the following to the LTI application:

See if we can select the following paragraph:

{"Characters": 339, "Textatistic.counts": {"polysyblword_count": 0, "word_count": 64, "sent_count": 6, "notdalechall_count": 10, "sybl_count": 79, "char_count": 272}, "Textatistic.flesch_score": 91.58020833333336, "Junk": "Chip", "Words": 64}

This passes the following to the LTI application:
