To calculate an approximate value for, say 99.55, you could first rewrite it as
1005*(1-0.005)5
and then use the binomial expansion of the first three terms of (1-0.005)5 to get a pretty good approximation - accurate to 1.2 parts in a million!
You can calculate the first three terms without a computer if you know your basic times tables.
The binomial theorem describes the algebraic expansion of powers of a binomial, hence it is referred to as binomial expansion.
Binomial Theorum
A binomial coefficient is a coefficient of any of the terms in the expansion of the binomial (x+y)^n.
The first two terms in a binomial expansion that aren't 0
Binomial Expansion makes it easier to solve an equation. It brings an equation of something raised to a power down to a solveable equation without parentheses.

Sounds pretty sexy, eh? See link. http://en.wikipedia.org/wiki/Binomial_expansion
The binomial expansion is valid for n less than 1.

Not true. The expansion will have one more term.
Binomial Expansion makes it easier to solve an equation. It brings an equation of something raised to a power down to a solveable equation without parentheses.
The binomial theorem describes the algebraic expansion of powers of a binomial: that is, the expansion of an expression of the form (x + y)^n where x and y are variables and n is the power to which the binomial is raised. When first encountered, n is a positive integer, but the binomial theorem can be extended to cover values of n which are fractional or negative (or both).

For binomial expansions. (When you have to multiply out many brackets, binomial expansion speeds things up greatly).
