Fluently add and subtract multi-digit whole numbers using the standard algorithm.

Having a Glossary meant I could reduce the text on most pages, while expanding background for the definitions, and relating the ideas to other similar, contradictory, or more basic ideas. Why Bother with Definitions? The value of a definition is insight.

Simple descriptions are not always possible. Terms have meaning within particular contexts. Tedious examples may be required to expose the full meaning. Good definitions can expose assumptions and provide a basis for reasoning to larger conclusions. Consider the idea that cryptography is used to keep secrets: We expect a cipher to win each and every contest brought by anyone who wishes to expose secrets.

We call those people opponentsbut who are they really, and what can they do? In practice, we cannot know. Opponents operate in secret: We do not know their names, nor how many they are, nor where they work.

We do not know what they know, nor their level of experience or resources, nor anything else about them.

Because we do not know our opponents, we also do not know what they can do, including whether they can break our ciphers. Unless we know these things that cannot be known, we cannot tell whether a particular cipher design will prevail in battle.

We cannot expect to know when our cipher has failed. Even though the entire reason for using cryptography is to protect secret information, it is by definition impossible to know whether a cipher can do that.

Nobody can know whether a cipher is strong enough, no matter how well educated they are, or how experienced, or how well connected, because they would have to know the opponents best of all. The definition of cryptography implies a contest between a cipher design and unknown opponents, and that means a successful outcome cannot be guaranteed by anyone.

Sometimes the Significance is Implied Consider the cryptographer who says: First, the cryptographer has the great disadvantage of not being able to prove cipher strength, nor to even list every possible attack so they can be checked.

In contrast, the cryptanalyst might be able to actually demonstrate weakness, but only by dint of massive effort which may not succeed, and will not be compensated even if it does.Skip to main content Journals Books Register Sign in. Comments. Comments are supported as follows: a # may appear in most places in a line and gnuplot will ignore the rest of the line.

It will not have this effect inside quotes, inside numbers (including complex numbers), inside command substitutions, etc. Apr 17, · Use the division algorithm to find the quotient and remainder when f(x) is divided by g(x), over the indicated field.

List all monic irreducible polynomials of degree lees than or equal to 3 over Z3. Write each of the following polynomials as a product of irreducible polynomials: a) x^2 - 2x + 1 b) x^4 + 2x^2 + 2x + 2 c) 2x^3. Indecision and delays are the parents of failure.

The site contains concepts and procedures widely used in business time-dependent decision making such as time series analysis for forecasting and other predictive techniques.

In mathematics and computer algebra, factorization of polynomials or polynomial factorization is the process of expressing a polynomial with coefficients in a given field or in the integers as the product of irreducible factors with coefficients in the same domain.

Polynomial factorization is one of the fundamental tools of the computer algebra systems.. The history of polynomial factorization. UNIT I.
