Addition and subtraction can be performed on 2D arrays.

Explanation:
- 2D arrays, also known as matrices, are rectangular arrangements of elements organized in rows and columns.
- Addition and subtraction are arithmetic operations that can be performed on 2D arrays.
- When adding or subtracting two 2D arrays, the corresponding elements in the arrays are added or subtracted.
- For example, if we have two 2D arrays A and B, the sum of A and B, denoted as A + B, is a new 2D array where each element is the sum of the corresponding elements in A and B.
- Similarly, the difference of A and B, denoted as A - B, is a new 2D array where each element is the difference of the corresponding elements in A and B.
- The addition and subtraction operations can be performed on any two 2D arrays as long as they have the same dimensions (i.e., the same number of rows and columns).
- The resulting 2D array will have the same dimensions as the original arrays.
- The addition and subtraction operations are useful in various applications, such as mathematical calculations, image processing, and data analysis.
- They allow us to combine or compare the values in different 2D arrays to obtain meaningful results.
- In contrast, multiplication and division are not defined for 2D arrays in the same way as they are for scalar values or vectors.
- Concatenation and splitting are operations that involve combining or separating different parts of 2D arrays, and they are not directly related to arithmetic operations.
- Sorting and searching are operations that involve arranging the elements of a 2D array in a specific order or finding specific elements in the array, but they do not involve arithmetic operations.
