\begin{definition}[Definition:Array/Element]
Let $\mathbf A$ be an Array.
The individual $n \times n$ symbols that go to form $\mathbf L$ are known as the '''elements''' of $\mathbf L$.
The '''element''' at row $i$ and column $j$ is called '''element $\tuple {i, j}$ of $\mathbf A$''', and can be written $a_{i j}$, or $a_{i, j}$ if $i$ and $j$ are of more than one character.
If the indices are still more complicated coefficients and further clarity is required, then the form $a \left({i, j}\right)$ can be used.
Note that the first subscript determines the row, and the second the column, of the array where the '''element''' is positioned.
