### Instruction: Cory made a complete list of the prime numbers between 1 and 25. What is the sum of the smallest prime number and the largest prime number on his list?### Response: A prime number is a natural number that has exactly two positive factors: 1 and itself.
The smallest prime number is 2, since 1 is not considered a prime number.
The largest prime number between 1 and 25 is 23, since 25 is not prime (it is divisible by 5).
To find the sum of the smallest and largest prime numbers on Cory's list, I just need to add 2 and 23.
