a prime number is a number that you can plus by one
(2X3X5X13X17) + 13 = 6643 This is a composite number.
Composite, because it has other factors except 1 and itself. Plus it's an even number and all even numbers are composite (except 2).
110 + 120 = 330 330 is a composite number.
The sum of these composite numbers, including 100, is 3989.The sum of all numbers between 1 and 100 is 5,050. From this we need to subtract the sum of 1 plus all the prime numbers below 100. The sum of the primes is 1,060. Subtracting (1 + 1060) or 1,061 from 5,050 yields 3,989.
71113 + 13 = 71126 7654321 + 5 = 7654326 Both can be divided by numbers other than 1 and itself. Hence both are composite.
The first number is odd, the second is odd. Odd + Odd = Even ie the sum is even. Either number is greater than 2 so their sum is greater than 2. All even numbers greater than 2 are composite.
5+5+8+111+9+7654321=7654459Every operation in this problem is addition. This means that all the adding can be done in one step.

They are two composite numbers that can be quite easily added together by means of a calculatoror or by hand.
8 + 16 = 24. 24 is a composite number because it is divisible by numbers other than 1 and itself. For example, it is an even number, which means it is divisible by 3.
97 plus 101 198
(2X3X5X13X17) + 13 = 6643 This is a composite number.
1, 5, 7, 35, composite
In order to figure that out, you must know a and b. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 have a different name.
Composite, because it has other factors except 1 and itself. Plus it's an even number and all even numbers are composite (except 2).
As all prime numbers greater than zero are odd, p plus 1 would always be even, therefore always be dividable by 2 and therefore not prime
