Now that you know the core principles of arithmetic and geometry, you're ready to move on to learning advanced skills that will allow you to explore more aspects of God's creation. In Book 2, the focus is on the essential principles of algebra, coordinate graphing, probability, statistics, functions, and other important areas of mathematics. Here at last is a math curriculum with a biblical worldview focus. Some mathematical terms seem so complex, but don't worry; they're just fancy names to describe useful tools. In Book 2 you'll continue discovering that all of math boils down to a way of describing God's world and is a useful means we can use to serve and worship Him.
