In its most general sense, an algorithm is any set of detailed instructions which results in a predictable endstate from a known beginning. Algorithms are only as good as the instructions given, however, and the result will be incorrect if the algorithm is not properly defined.
A common example of an algorithm would be instructions for assembling a model airplane. Given the starting set of a number of marked pieces, one can follow the instructions given to result in a predictable endstate: the completed airplane. Misprints in the instructions, or a failure to properly follow a step, will result in a faulty end product.
A computer program is another pervasive example. Every computer program is simply a series of instructions, which may vary in complexity, and is listed in a specific order, designed to perform a specific task. Mathematics also uses algorithms to solve equations by hand, without the use of a calculator. One last example is the human brain: most conceptions of the human brain define all behavior — from the acquisition of food to falling in love — as the result of a complex algorithm.
While there is no universally accepted breakdown for the various types of algorithms, there are common classes that algorithms are frequently agreed to belong to. Among these are:
In addition to these general classes, algorithms may also be divided into two primary groups: serial algorithms, which are designed for serial execution, wherein each operation is enacted in a linear order; and parallel algorithms, used with computers running parallel processors, wherein a number of operations are run parallel to each other. Parallel algorithms also exist in the natural world in the case of, for example, genetic mutation over a species.

write an algorithm for a program that prompts the user to enter five test scores, calculate the total of the five tests and find the weighted average of each test assuming that each tests weighs 20 percent.

An algorithm is like a predetermined pattern to be followed for a predetermined result. A common algorithm of a rubik's cube is down, left, up, side. Obviously, it is much more complex to solve the rubik's. There are about 56 algorithms to follow. Hope this helps.

Given a problem (i.e. a question, such as "What is 2+2?" or "What are the prime factors of 1729?") an algorithm is a description of a method for a computer to answer that problem. Another way to think of it is that some mathematical proofs (e.g. the proof of the Chinese Remainder Theorem) are "constructive"; they give procedures for calculating the values which satisfy the theorem. Such procedures, if they can be expressed to a computer, are in fact algorithms.

Why can algorithms be known as steps? It is because i'm doing a science project which i have to devise an algorithm to figure out a rubiks cube. Is it possible? what is it?
