Several Answers - As the total of 110 is an even number, then the prime number "2" must be one of the numbers as three odd prime numbers would add up to an odd number total. The question can then be regarded as , What 2 prime numbers add up to 108 ? 103 + 5 + 2 101 + 7 + 2 97 + 11 + 2 89 + 19 + 2 79 + 29 + 2 71 + 37 + 2 67 + 41 + 2 61 + 47 + 2
To make 11, you can simply add the numbers 5 and 6 together (5 + 6 = 11). Alternatively, you could use the numbers 2 and 9 (2 + 9 = 11) or even multiply 1 by 11 (1 × 11 = 11). There are various combinations of numbers that can sum up to 11.
