1. **State the problem:** Evaluate the permutation expression $7P2$.
2. **Recall the formula for permutations:**
$$nP r = \frac{n!}{(n-r)!}$$
where $n$ is the total number of items, and $r$ is the number of items to arrange.
3. **Apply the formula:**
$$7P2 = \frac{7!}{(7-2)!} = \frac{7!}{5!}$$
4. **Calculate factorials:**
$$7! = 7 \times 6 \times 5!$$
So,
$$\frac{7!}{5!} = \frac{7 \times 6 \times 5!}{5!}$$
5. **Cancel common factors:**
$$= 7 \times 6 = 42$$
6. **Interpret the result:** The value is an integer.
**Final answer:**
$$7P2 = 42$$
