None. Any two odd numbers add up to an even number.
Two is the only even prime number. When you add an odd number to another odd number, you get an even number. When you add an even number to an odd number, you get an odd number. 91 is an odd number, therefore the answer is 2 and 89.
As long as one of the numbers isn't 2, adding any two prime numbers results in an even number. Why? 1.) Adding any two odd numbers gives an even number, 2.) adding an odd and an even gives an odd, and 3.) all primes are odd, except for 2.
no, b/c you can think of an odd number as an even number plus one. So if you add two odd numbers, you would be adding 2 even numbers plus 2... Let # be even... (#+1) + (#+1) = (#+#) + 2 two even numbers added together are always even
list 1st 1 odd number, then add them. list 1st 2 odd numbers, then add them. list 1st 3 odd numbers, then add them. list 1st 4 odd numbers, then add them. look for a pattern. make a conjecture.
odd even numbers end in 2 , 4 , 6 , 8 , 0 odd numbers end in 1 , 3 , 5 , 7 , 9
You get an odd number.(i.e. 1+2=3)
Yes, after every even number, there is an odd. Odd number+ even number=odd number. For example: 1+2=3 , 2+3=5, 3+4=7
false even not odd 7 + 3 = 10 41 + 5 = 46 and so on ... . when you add 2 odd numbers your answer will always be even
The odd numbers 1-99 will be a higher total than the even numbers 2-98
Think of an odd number as an even number with 1 left over. So if you add two even numbers that each have 1 left over, the left overs add up to 2. So it's two even numbers added together plus 2.
Yes. Try it right now. Any two odd numbers, add them together.
Only if they are odd.
It could any odd prime number and 2 since 2 is the only even prime number and add whole numbers to an odd sum requires both odd and even.In other words, 2 and any other prime will work.
no...all even numbers that are added together are even.
No answer exists. Any 2 consecutive numbers will produce an odd sum.
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
All even numbers are multiples of 2, so they have 2 in their prime factorization. No odd numbers are divisible by 2, so no add number has 2 in its prime factorization.
No, they do not. If one of the prime numbers is 2, you will have an odd number.
No, as all prime numbers are odd, excluding 2, and when you add two odd numbers you get an even number. This even number can't be a prime number as it will be divisible by 2. 101 and 31 are both prime, but 101+31 is 132.
You need an odd and an even to get an odd. 2 odds can make and odd or an even. Simply, it's just a pattern.
You don't always. 2 + 5 = 7, for example. But all prime numbers other than 2 are odd and two odd numbers always equal an even number when added together.
