u have to add 1 add 1
You may mean: 3 and 5 are prime numbers that add up to the composite number of 8
17
41-- Less than 100-- 42 is the multiple of 7-- 4 + 1 = 5
It is impossible for three prime numbers less than 30 to add up to 1955. After all, 30+30+30 is only 90.
An even number because every prime number gretaer than 2 is odd.
A prime number, since nothing can add up to it.It has no factors other than itself and one.
You can get another prime (only if one of the numbers added is 2), for example, 101 + 2 = 103. If you add together two odd prime numbers, you will get an even number, which will not be a prime number. (An even number is a number that is divisible by 2; if such a number is greater than 2, it is not a prime number.)
You could add a negative number. ex. 98 + -100 = -2
Assuming that you want an integer (a whole number) less than 300, then the number you'll be looking to reach is 299. To get to 299 from 176 you need to add 123.
