... 35. A castle in the far away land of Notsuoh was surrounded by four moats. One day the castle was attacked and captured by a fierce tribe from the north. Guards were stationed at each bride over the moats. Johann, from the castle, was allowed to take a number of bags of gold as he went into exile. H ...

3 Solving Equations
... balance, but we want to move toward a simple equation in which the solution is obvious. As we will see later, this is not always possible. What operations can we perform that will always keep the pans in balance? In other words, what can be done to move from one equation to another equation so that ...

Elementary mathematics
Elementary mathematics consists of mathematics topics frequently taught at the primary or secondary school levels. The most basic topics in elementary mathematics are arithmetic and geometry. Beginning in the last decades of the 20th century, there has been an increased emphasis on problem solving. Elementary mathematics is used in everyday life in such activities as making change, cooking, buying and selling stock, and gambling. It is also an essential first step on the path to understanding science.In secondary school, the main topics in elementary mathematics are algebra and trigonometry. Calculus, even though it is often taught to advanced secondary school students, is usually considered college level mathematics.
