If the two prime numbers are different: You get the two prime numbers, plus 1, plus the product. For example, if you multiply 2 x 3 = 6, the factors of 6 are 2, 3, 1, and 6. If the two prime numbers are the same: You get the prime number, 1, and the product. For example 2 x 2 = 4. The factors of 4 are 2, 1, 4.

No. The sequence of numbers we're given are odd numbers, and the sum of any three odd numbers will always be an odd number itself. Because 30 is an even number, you can not pick any three odd numbers that will add up to it.


What does a negative number plus a positive number equal?

In this case, it would depend on how high thepositive number is. for example: negative 10 plus positive 12 would equal positive 2 because the ten negative numbers would cancel out ten of the positive twelve numbers. So the answer would be a positive number but ONLY IF you could take the sign away from the number and the positive number was higher.
