An invisible world of astonishing complexity is all around you. A world so small you can't see it with the naked eye. A world so crowded that its population staggers the mind. A world in which you participate every day—often without even knowing it.
Algebra II is the fork in the road. Those who succeed in this second part of the algebra sequence are well on their way to precalculus, calculus, and higher mathematics, which open the door to careers in science, engineering, medicine, economics, information technology, and many other fields. And since algebraic thinking is found in almost every sphere of modern life, a thorough grounding in this abstract discipline is essential for many nontechnical careers as well, from law to business to graphic arts.
Algebra I is one of the most critical courses that students take in high school. Not only does it introduce them to a powerful reasoning tool with applications in many different careers, but algebra is the gateway to higher education. Students who do well in algebra are better prepared for college entrance exams and for college in general, since algebra teaches them how to solve problems and think abstractly—skills that pay off no matter what major they pursue.
If there exists a Fountain of Youth, exercise is it. The evidence, of course, is vast, with a multitude of studies highlighting the remarkable, life-enhancing benefits of staying fit.

This is the story of a country in which immigrants of the late 19th and early 20th centuries huddled in cramped tenement apartments lit by hazardous kerosene lamps. And a country that, little more than a half-century later, renowned economist John Kenneth Galbraith described as "The Affluent Society." This is the chronicle of a nation that enslaved a race of people. And of a nation that fought a Civil War that freed its slaves, and outlawed segregation and discrimination. This is history shaped by Revolutionary War and Vietnam, Thomas Jefferson and William Jefferson Clinton, Puritanism and Feminism, Booker T. Washington and Martin Luther King, Jamestown and Disneyland, Harpers Ferry and Henry Ford, oil wells and Orson Welles.
