Exponential and logarithmic functions
... The logarithm with base 10 is called the common logarithm and is denoted by omitting the base: log x = log10 x. Thus, y = log x if and only if x = 10 y. Applying the basic properties of logarithms ...

Supplemental Problems and Solutions for MTH 112
... Recall that there are two distinct square roots of any positive real number (e.g., the two square roots of 4 are 2 and –2). The same is true for any complex number. We can find two different square roots of a complex number by using two different polar forms of the number. To find polar forms of −1 ...

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.
