Properties of Exponents
... Whenever mathematicians define a symbol or concept on a subset of the real numbers, they like to extend it to bigger sets of the real numbers, and if possible to the whole real number system. So let’s try to extend the definition of exponents to the whole numbers = {0, 1, 2, 3, ….}. The only number ...

Multiplying large numbers - lattice method
... - lattice method Let’s look at another multiplication equation worked out using the lattice method. With this method, you multiply each number in the column by each number in the row. Then you add along the diagonals to get the answer. Have a look at this equation: 25 x 5 ...

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.
