Annotation: Rules of symmetry of mathematical actions allow to apply a commutative law to all mathematical actions: to addition, deduction, multiplication and division. (An annotation is this obligatory condition for the publication of the article. Such are rules of the bureaucratic playing science)
Changes in the surrounding world are expressed by mathematical actions. Quantitative changes are expressed by addition and deduction. Quality changes are expressed by an increase and division. No quantitative changes can cause the change of quality.
Quantitative changes reflect the change of amount of the separately taken unit. Addition and deduction are symmetric mathematical actions reflecting the quantitative changes of any unit. Addition and deduction are mirror symmetric relatively neutral element are points zero.
An increase and division similarly are symmetric mathematical actions reflecting the quality changes of units. An increase and division are back symmetric relatively neutral element are points one.
Rules of symmetry of mathematical actions:
1. Any mathematical action is begun with a neutral element.
2. A sign of mathematical action is the inalienable attribute of number before that he stands. (This fragment is distinguished by me by fat text specially for you)
Application of these rules allows to apply a commutative law to all mathematical actions reflecting quality or quantitative changes.
0 + 3 + 7 + 4 = 0 + 7 + 3 + 4 = 14
0 – 3 – 7 – 4 = 0 – 7 – 3 – 4 = –14
0 + 3 – 7 – 4 = 0 – 7 + 3 – 4 = –8
1 х 3 х 7 х 4 = 1 х 7 х 3 х 4 = 84
1 : 3 : 7 : 4 = 1 : 7 : 3 : 4 = 1/84
1 х 3 : 7 : 4 = 1 : 7 х 3 : 4 = 3/28
A commutative law can not be used in the cases of the mixed implementation of mathematical actions reflecting quality and quantitative changes in one mathematical expression.
The change of the mathematical operating on symmetric gives a symmetric result, here the point of symmetry is a neutral element. Application of commutative law does not influence on a result.
0 – 3 – 7 – 4 = 0 – 7 – 3 – 4 = –14
0 + 3 + 7 + 4 = 0 + 7 + 3 + 4 = 14
0 – 3 + 7 + 4 = 0 + 7 – 3 + 4 = 8
1 : 3 : 7 : 4 = 1 : 7 : 3 : 4 = 1/84
1 х 3 х 7 х 4 = 1 х 7 х 3 х 4 = 84
1 : 3 х 7 х 4 = 1 х 7 : 3 х 4 = 28/3
Running the numbers in the mathematical operating on symmetric relatively neutral element of number gives a symmetric result.
0 + (–3) + (–7) + (–4) = 0 + (–7) + (–3) + (–4) = –14
0 – (–3) – (–7) – (–4) = 0 – (–7) – (–3) – (–4) = 14
0 + (–3) – (–7) – (–4) = 0 – (–7) + (–3) – (–4) = 8
1 х 1/3 х 1/7 х 1/4 = 1 х 1/7 х 1/3 х 1/4 = 1/84
1 : 1/3 : 1/7 : 1/4 = 1 : 1/7 : 1/3 : 1/4 = 84
1 х 1/3 : 1/7 : 4 = 1 : 1/7 х 1/3 : 1/4 = 28/3
Simultaneous change of the mathematical operating on symmetric and running the numbers on symmetric relatively neutral element of number abandons a result without changes.
0 – (–3) – (–7) – (–4) = 0 – (–7) – (–3) – (–4) = 14
0 + (–3) + (–7) + (–4) = 0 + (–7) + (–3) + (–4) = –14
0 – (–3) + (–7) + (–4) = 0 + (–7) – (–3) + (–4) = –8
1 : 1/3 : 1/7 : 1/4 = 1 : 1/7 : 1/3 : 1/4 = 84
1 х 1/3 х 1/7 х 1/4 = 1 х 1/7 х 1/3 х 1/4 = 1/84
1 : 1/3 х 1/7 х 4 = 1 х 1/7 : 1/3 х 1/4 = 3/28
The neutral elements of mathematical actions it is not accepted to write at the decision of mathematical problems and examples, as they do not influence on a result. Before application of commutative law introduction of neutral elements allows correctly to apply a commutative law.
All of it is written, certainly, not for blondes, and for mathematicians. In the future we yet not once will call to this article. And while... you know any more mathematician about symmetry of mathematical actions.
