But, apparently, this method is rather cumbersome. Therefore, there can be suggested another, easier way to do this, but without claiming of its superfluous rigidity.

Newton entrusted, so, why not 2, 5, 7.65-choose any). So, without logical explanation these are looking a little mysterious or sometimes even magic. This article is a humble attempt to get it straight rather formally. Some troubles may appear on the way-e.g. as it was shown earlier (in the ref. [2], for example), there are at least two binary relations having properties of idempotent equivalences-algebra's elements that may aspire to be an identity. Apparently, probable obtaining of some well-known results in the text is not an attempt of their rediscovering , but it is rather "check-points" that confirm theory validity, more by token that it was made by using of the only exceptionally formal way, while usually they are obtained rather intuitively. Usually the notion of tensor product is determined for each kind of algebraic structure-especially for modulus (in group theory it is often called direct product-but this is a matter of semantics, so, it's rather negligible). Here it is shown that tensor product may be introduced without defining of concrete algebraic structure. Without such introduction defining of algebraic operation is strongly complicated.

There was paid an attention only for natural relations. In fact, such relations as "better than" are not observed here since the notion of "good" is still not defined.

Unified definitions of different symmetry and reflexivity manifests were made. It was shown that among relations’ properties only transitivity has the direct negation.
