[AI-generated answer — Bot GPT 3.5]

In mathematics, "for" is often used to indicate a variable that is being iterated over in a sum or product. For example, in the expression "sum for i from 1 to n", the variable i is being summed over from 1 to n.

On the other hand, "@" is not commonly used in mathematical notation. However, in some programming languages, like MATLAB, "@" is used to denote matrix multiplication. For example, in MATLAB, A @ B represents the matrix product of matrices A and B.
