How do I type math? The way you write it: 3/4 + 5/6, x^2 - 5x + 6 = 0, sqrt(50), sin(30°). Use ^ for powers. The math keypad has every symbol.
How do I start over? Tap the red Clear button in the top-right of the display.
What does it cost? Free to download, and the first 7 days are full access. Then the first Algebra 1 unit, the grapher and the unit-circle lab stay free, and full access is $5 a month (or $10 a month for every Pocket Professor app plus Pocket Parker Premium). Cancel any time.

Instructors: Practice, then "make a problem set to share" gives a link and QR code; every student gets the same problems.
