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. Well again touch on systems of equations, inequalities, and functions...but well also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Dont let these big words intimidate you. Were on this journey with you!
