Con l'inserimento di valori appropriati nei membri di sinistra di queste uguaglianze, si possono produrre degli 0 nei membri di destra: Le regole qui sopra sarebbero pertanto errate se 0 non fosse pari. Da un'altra prospettiva, prendendo le regole rispettate dai numeri pari positivi e richiedendo che continuino a funzionare per tutti gli interi si arriva alla conclusione che zero deve essere pari. Il lemma afferma che un certo tipo di colorazione su una triangolazione di un simplesso ha un sottosimplesso che contiene tutti i colori della colorazione.
Questa definizione ha il vantaggio concettuale di basarsi solo sugli assiomi minimali dei numeri naturali: Per determinare se un punto giace all' interno di un poligonosi considera una semiretta dal punto all' infinito e si conta il numero di volte che la semiretta interseca il bordo del poligono. Ogni volta che la semiretta incrocia il poligono il numero di intersezioni si alterna tra pari e dispari e il punto tra interno ed esterno. Queste classi laterali possono essere descritte come classi di equivalenza della seguente relazione di equivalenza: Gli elementi del gruppo alternante, dette permutazioni parisono i prodotti di un numero pari di trasposizioni.
Nell'insieme dei numeri 2-adici tale successione convergein effetti, a 0. Highly effective people have learned to stave off procrastination; just how have they done this? The following suggestions may help you get out of the cycle—and may help you set a good example for those with whom you interact. By using specific, concrete steps, you can confront and diminish your own tendency to procrastinate.
Take a close look at your own procrastination. Do you put off similar tasks every month, such as paying your bills?
Or do you postpone every task, no matter how small? Recognizing the self-defeating cycle of procrastination is often a motivator in itself. Procrastinators often cannot enjoy a personal life like others. They often end up working late and at odd hours, leaving them tired, cranky, and behind on all the other work that is piling up.
Commit to improve your procrastination habits to yourself. Losing face can be a powerful motivator. Discover your pattern of procrastination, and note when and where you use procrastination as a crutch. Consider the following possible sources for procrastination and how they can be overcome: Fear—Some procrastinators actually fear doing the task or project at hand because the task or project requires them to move out of their comfort zone.
The thought of doing something different or unknown freezes them into immobility. For example, when people defer making phone calls, they may do so because they fear that the other party may not like what they have to say or will somehow reject them. Becoming aware of your fear can help you eliminate it.

Write down your strengths and skills; then recall previous successes. By becoming aware of and acknowledging your weaknesses, you can leverage them into strengths.
A coach or mentor can help you identify weaknesses that are really hidden strengths. Focus on your own needs and expectations rather than those of others. Perfectionism—This is probably one of the more common reasons for procrastinating.COME ANDARE BENE A SCUOLA
Perfectionists avoid starting a task because they fear they might fall short of their own high standards. They sometimes become absorbed in the details of a project in an attempt to control it. As a result, they ignore moving it along until the very last minute: They don't have to face their fear of imperfection if the task is not done. If you suspect that you are a perfectionist, closely examine your standards and values. Are they really yours, or someone else's?
Are they set so high that they are causing you distress? Work at shifting your thinking about standards and values, and set realistic goals.

- How do you deal with procrastination?
Crisis making—If you have spent many years feeling thrilled or rewarded by being under time deadlines, you are probably a crisis-maker—one who thrives on adrenaline. Crisis-makers truly believe they cannot get motivated until the very last minute. As much as they complain about having no time, they get a charge out of running late for appointments, barely getting to the airport on time for a flight, and rushing from one unfinished project or task to another.
Often they make others mad because they manufacture a crisis and then solve it at the last minute. In so doing, they either make themselves look good, or they totally blow it, infuriating their friends and colleagues and making themselves look bad in the process. If this defines your style, you will have to work to bring balance to your life.
Learn how to develop a rewarding life outside of work. Avoid trying to get esteem or personal emotional needs met at work, and learn how to increase your productivity and quality of work while eliminating the adrenaline rush. Expectation anxiety—This is a tough one. If you stop trying to become a "better person" for other people, you'll realize that the person you are is just fine. Once you learn that your faults can be wonderful teachers, that mistakes are golden, and that your weaknesses are usually just hidden strengths, you begin to accept yourself.
Once you accept yourself, you realize that you always do your best and then the expectations of others become less important. Work with a coach or mentor to get past this one.

Overextending—Those who overextend themselves, the over-doers, have the hardest time recognizing themselves because to them, everything is important. Prioritizing, delegating and saying "no" are not the strong points of over-doers.
If you fit this description, identify what is necessary to accomplish the task in a given amount of time. Try to get a sense of the entire project and what is required to complete it. Set goals for what is to be accomplished and when, and break goals into smaller sub-goals. For example, concentrate on one section of a report at a time.
