It looks like you're asking for the summation of factorials from $x = 1$ to $x = 2$. The expression can be interpreted as:

$\sum_{x=1}^{2} x!$

This summation can be expanded as:

$1! + 2!$

Let's calculate each factorial:

$1! = 1$ $2! = 2 \times 1 = 2$

Now, sum these values:

$1 + 2 = 3$

So, the value of $\sum_{x=1}^{2} x!$ is $3$.

Would you like more details or have any other questions?

Here are some related questions:

1. What is the definition of a factorial?
2. How would the summation change for higher values of $x$?
3. What is the factorial of 0?
4. How is factorial used in permutations and combinations?
5. Can you find the sum $\sum_{x=1}^{3} x!$?

Tip: The factorial of a number $n$ is the product of all positive integers less than or equal to $n$.
