Description

Here are some cards I made while going through the Algebra I mission in Khan Academy. Latex required.

Sample (from 159 notes)

Cards are customizable! When this deck is imported into the desktop program, cards will appear as the deck author has made them. If you'd like to customize what appears on the front and back of a card, you can do so by clicking the Edit button, and then clicking the Cards button.
Front How would you solve the below for c?[$]c^2 = \frac{121}{169}[/$]
Back [$]\sqrt{c^2} = \pm \sqrt{\frac{121}{169}}[/$][$]c = \pm \sqrt{\frac{121}{169}}[/$][$]c = \pm \frac{\sqrt{121}}{\sqrt{169}}[/$][$]c = \pm \frac{11}{13}[/$]

After the file is downloaded, double-click on it to open it in the desktop program.

At this time, it is not possible to add shared decks directly to your AnkiWeb account - they need to be added from the desktop then synchronized to AnkiWeb.
