Okay the first picture is teacher, and the second is mine, am I wrong for not circling 1? or was I right? I let you choose  

You were **correct not to circle 1**.

In your teacher's explanation, the answer states that 1 is a prime number, but this is incorrect. Here's why:

### Definition of a Prime Number:
A prime number is a natural number greater than 1 that can only be divided by 1 and itself. Therefore, **1 is not a prime number** because it does not meet the criterion of being greater than 1.

Let's review the numbers:
- **1**: Not prime (since it's not greater than 1).
- **π**: Not prime (it's not even an integer).
- **5**: Prime (only divisible by 1 and 5).
- **9**: Not prime (divisible by 1, 3, and 9).
- **-5**: Not prime (negative numbers aren't prime by the usual definition of prime numbers).
- **7**: Prime (only divisible by 1 and 7).

So, the correct primes in your list are **5 and 7**, and you were right to leave 1 uncircled.

Here are 5 related questions for deeper understanding:
1. Why are negative numbers not considered prime?
2. Why is the number 1 a special case in prime number definitions?
3. Could π ever be considered prime under different rules?
4. What is the smallest prime number and why?
5. How do composite numbers differ from prime numbers?

Tip: Always remember, prime numbers start from 2, as 1 is neither prime nor composite!
