1. The problem is to find the expression for $2 \times A$ where $A$ is a variable or a given quantity. 2. Multiplying a variable by 2 means doubling its value. 3. Therefore, $2 \times A$ is simply written as $2A$. 4. This expression means that whatever the value of $A$ is, it is multiplied by 2. Final answer: $2A$
