ABSTRACT = {Commonsense reasoning plays a pivotal role in the development of intelligent systems for decisionmaking, system analysis, control and other applications. As Prof. L. Zadeh mentions a kernel of the 
theory of commonsense is the concept of usuality. Zadeh suggested main principles of the theory of 
usuality, unfortunately up to present day; a fundamental and systemic approach to reasoning with 
usual knowledge is not developed.<br/>
In this study, we develop a new approach to calculus of usual numbers (U-numbers). We consider a 
U-number as a Z-number, where the second component is “usually”. Validity of the suggested approach 
is verified by examples.},
