The two numbers that add to -11 and multiply to 19 are -10 and -1. When you add them together, -10 + (-1) equals -11. When you multiply them, -10 × -1 equals 10, not 19. Therefore, there are no two real numbers that satisfy both conditions simultaneously.

The two prime numbers that add up to 19 are 7 and 12. Prime numbers are numbers greater than 1 that can only be divided by 1 and themselves. In this case, 7 and 12 are not prime numbers, and there are no two prime numbers that add up to 19.
22 + 19 + 6 + 14 = 61
