Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Don't let these big words intimidate you. We're on this journey with you!

Finance and capital markets on Khan Academy: Buying a home involves a lot more than writing a check and getting keys. It could very well be the largest transaction that either the buyer or seller does in their life. Because that, it is an involved process that can sometimes be confusing. Whether we're talking title insurance, escrow, or contingencies, the goal of this tutorial is to demystify the process.

Geometry on Khan Academy: We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.

When we read a one-sided limit from a table, we are only interested in the value the function approaches from a single direction (either left or right).

Predator-prey population cycles demonstrate how populations of predators and prey interact and influence each other's growth. In general, as predator numbers increase, the prey population declines, leading to a decrease in predators. Over time, the prey population may begin to increase, restarting the cycle. The example of the snowshoe hare and Canadian lynx shows how predator and prey populations can vary in relation to one another.
