What is the Edform math equation editor?

The equation editor is the Formula button in Edform's text editor. Click it where the cursor is, then type 1/2 for a fraction, ^ for a power and sqrt for a root, or tap a math symbol. The formula appears in your text exactly as students will see it. It works in question prompts of every type, explanations and hints, worksheet fields, lesson slides, video notes, course texts and grading feedback, and formulas print correctly too. For answers, number questions accept a value with an optional tolerance and unit, so 3.14 ± 0.01 or 5 cm is graded for you.
