AB×C

AB×C is a notation that can represent different mathematical concepts depending on the context. Most commonly, it signifies the multiplication of three distinct entities, A, B, and C. In this interpretation, the '×' symbol explicitly denotes multiplication, meaning the result is the product of A, B, and C. This is a fundamental operation in arithmetic and algebra.

Alternatively, AB×C could refer to the composition of functions. If A, B, and C represent functions, then AB×C might indicate the sequential application of these functions. For instance, if we consider function composition from right to left, it could mean applying function C first, then applying function B to the result, and finally applying function A to that outcome. The notation for function composition is often represented with a small circle (∘), such as A∘B∘C, but in some informal contexts, the multiplication symbol might be used.

In abstract algebra, the notation could also relate to specific algebraic structures. For example, in group theory or ring theory, AB×C might denote a product of elements within a group or ring. The precise meaning would be dictated by the definitions of the operations and elements within that particular algebraic system. Without further context, the most straightforward interpretation remains the simple multiplication of A, B, and C.
