The two numbers that multiply to get 22 are 2 and 11. This is because 2 multiplied by 11 equals 22. These two numbers are the only pair of integers that multiply to give 22, as 22 is a prime number and cannot be factored into other integers.

There are millions of combinations of numbers with a difference of 9. 9 and 0, 10 and 1, 11 and 2, 12 and 3, and so on. The difference is the answer that you get when you subtract two numbers, so any numbers that subtract to an answer of 9 will work.

11
The two numbers that multiply to get 11 are 1 and 11. Since 11 is a prime number, it only has these two positive factors. Additionally, -1 and -11 also multiply to 11, as the product of two negative numbers is positive.

The two numbers that multiply to get 22 are 2 and 11. This is because 2 multiplied by 11 equals 22. These two numbers are the only pair of integers that multiply to give 22, as 22 is a prime number and cannot be factored into other integers.
The two 2-digit numbers that multiply to make 176 are 11 and 16. When you multiply 11 by 16, you get 176 (11 × 16 = 176). These are the only two-digit integers that satisfy this condition.

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 numbers that multiply to 42 and add up to 11 are 14 and -3. Specifically, 14 × -3 = -42 and 14 + (-3) = 11.
