Multiple Choice

Sum the prime numbers less than 10.

Explanation:
Primes are numbers greater than 1 that have exactly two divisors: 1 and the number itself. Under 10, the primes are 2, 3, 5, and 7. Add them: 2 + 3 = 5, 5 + 5 = 10, 10 + 7 = 17. So the sum is 17. Since 1 and 9 are not prime, there aren’t any other primes to add, making 17 the correct total.
