The purpose of this paper is to present the terms of grey numbers and its operations.
The definitions of elementary terms about grey numbers and its operations are presented one by one.
The reader could know the basic explanation about the important terms about grey numbers and its operations from this paper.
Many of the colleagues thought that unified definitions of key terms would be beneficial for both the readers and the authors.
It is a fundamental work to standardise all the definitions of terms for a new discipline. It is also propitious to spread the universal principles of grey system theory.
