This handbook supplies a collection of mathematical formulas and tables which will be valuable to students and research workers in the fields of mathematics, physics, engineering, and other sciences.
If n is a positive integer the series terminates and is valid for all x: the term in xr is nCrxr or n r where nC r n! r!(n r)! is the number of different ways in which an unordered sample of r objects can be selected from a set of n objects without replacement. When n is not a positive integer, the series does not terminate: the innite series ...

calculations which involve positive and negative numbers? Are there any rules which help us? We start with some revision — all real numbers are either positive or negative (or, of course, zero). The positive numbers are those greater than zero, and the negative ones are those less than zero.
Indices or Powers. mc-TY-indicespowers-2009-1. A knowledge of powers, or indices as they are often called, is essential for an understanding of most algebraic processes. In this section of text you will learn about powers and rules for manipulating them through a number of worked examples.
A function is a rule which maps a number to another unique number. In other words, if we start off with an input, and we apply the function, we get an output. For example, we might have a function that added 3 to any number. So if we apply this function to the number 2, we get the number 5.
