Read math equations
VoiceOver can read aloud math equations encoded using:

MathML or LaTeX in iBooks Author
Hear an equation. Have VoiceOver read the text as usual. VoiceOver says “math” before it starts
reading an equation.
Explore the equation. Double-tap the selected equation to display it full screen and move
through it one element at a time. Swipe left or right to read elements of the equation. Use the
rotor to select Symbols, Small Expressions, Medium Expressions, or Large Expressions, then swipe
up or down to hear the next element of that size. You can continue to double-tap the selected
element to “drill down” into the equation to focus on the selected element, then swipe left or
right, up or down to read one part at a time.
Equations read by VoiceOver can also be output to a braille device using Nemeth code, as well
as the codes used by Unied English Braille, British English, French, and Greek. See Support for
braille displays on page 160.
