You can add 3 numbers (or any quantity of numbers) and get a sum.
The two numbers that multiply to -15 and add up to 2 are 5 and -3. When you multiply 5 and -3, you get -15, and when you add them together, you get 2.

The numbers are: 9 and -6
The numbers are 3 and 4
Add the 3 numbers together, and then divide the total by 3. This will give you the median number.

Add all the numbers together; divide by the amount of numbers (for example, if you add three numbers, add the sum by 3).

When you add together three consecutive numbers, the result is always a multiple of three. This is because the sum can be expressed as (n + (n + 1) + (n + 2) = 3n + 3), which simplifies to (3(n + 1)). Thus, the sum is three times some integer, confirming that it is divisible by three.
