From 11:00PM PDT on Friday, July 1 until 5:00AM PDT on Saturday, July 2, the Shmoop engineering elves will be making tweaks and improvements to the site. That means Shmoop will be unavailable for use during that time. Thanks for your patience!
Some notation will be new in Algebra II. These include the dreaded matrix notation (disclaimer: it isn't that bad) and sigma notation. Others notations aren't so new, but we may have put them on the shelf hoping they'd never re-appear. Too bad—they're back. Exponents, roots, powers, and logarithms will all make an appearance.
