The two numbers that multiply to -30 and add up to 13 are 15 and -2. When you multiply 15 and -2, you get -30, and when you add them together, you get 13.

It is impossible for three prime numbers less than 30 to add up to 1955. After all, 30+30+30 is only 90.
Three numbers that are the same and equal 60 but are not 20 are 30, 30, and 30. This is because when you add 30 + 30 + 30, you get 90, which is the total sum of the three numbers. Each number is equal to 30, not 20, and when combined, they add up to 90, not 60.
None add up to 30; you would need at least three 6-sided die with numbers 6-11 to add to 30.
They are 29, 30 and 31.

93, 2, 1 are three numbers that add up to 96

Can not be done! An odd number of odd numbers will ALWAYS add up to an odd number.
