Equatio works seamlessly with our PDF tool called OrbitNote.  To get started, simply select the Screenshot Reader and pull a box around the math inside the PDF.  Listen to the audio playback and then select the ‘More’ button to choose ‘Edit with Equatio.’  This will pull the problem into the editor, and then its up to you to select the input method of choice and show your work to solve.  When finished, just insert that Math or STEM right back into OrbitNote for your teacher or professor to see.
