Users of Equatio can type out as many lines of text as they wish when using the product. Keep in mind, the equation editor inside Equatio is unable to text wrap. When typing on a line, you should identify a good stopping point for how many words you enter on a line. I would suggest no more than 12 words. Tap the Enter or Return key to make a second line of text & math. Again, follow the rule above to make math and text on line 2 and future lines within the product so things appear properly when you go to make your insert.
