What is the sum of the prime numbers less than 12?

Explanation:
Prime numbers are numbers that have exactly two divisors: 1 and themselves. Below 12, they are 2, 3, 5, 7, and 11. (1 isn’t prime, and 4, 6, 8, 9, and 10 aren’t prime.) Add them step by step: 2 + 3 = 5, 5 + 5 = 10, 10 + 7 = 17, 17 + 11 = 28. Therefore, the sum of the primes less than 12 is 28.
