Using MathML provides the highest level of accessibility.  You can acquire it easily by utilizing our SSR built right into the Equatio toolbar.  Click on the ‘Screenshot Reader.’  Draw a box around the math that you wish to capture the MathML of. Click on ‘More Options’.  Choose ‘Copy MathML.’  This will copy the MathML on your clipboard and you may then go paste the MathML into the integration of your choice.  Remember the receiving integration must be able to interpret the MathML in order for the math to display properly.
