Why do all numbers other than square numbers have an even number of factors?
Factors come in pairs. It is only in the case of a square number that the two middle factors are equal and so are counted only once.
Will pairs of even numbers ever make an odd number?
It depends on what you mean by "make." If you add, subtract, or multiply two even numbers, the answer is always an even number. But if you divide, the answer is not always even: 6/2 = 3 14/2 = 7
Multiplying an even number of negative numbers gives an answer that is?
Multiplying an even number of negative numbers results in a positive number. This is because each pair of negative numbers multiplies to give a positive product, and with an even count, all pairs will cancel out the negativity. Therefore, the final result will be positive.
How many pairs of even numbers can you find whose sum is eighteen?
2 + 164 + 146 + 128 + 104 pairs of even numbers can be found whose sum is eighteen.
9999555533331111 in these any six numbers total is 21 what are those numbers?
5+5+5+5+1 That is only 5 numbers being added. There can be no answer for six numbers for the following reasons: The numbers are all odd. Two odd numbers make an even number. Two even numbers make an even number. 21 is odd. Take 6 odd numbers and add them up in pairs. Each pair of odd numbers gives an even number so there are 3 even numbers. Even + Even + Even = Even. So sum of any six odd numbers is even but 21 is not even.
What 7 odd numbers that will total 30?
You cannot do this, because you're taking odd numbers: if you add two odd numbers together, you will get an even number. Take the odd numbers in pairs, so you'll have 3 pairs plus an extra odd number. The 3 pairs make 3 even numbers. You can add up any number of even numbers and get an even number, so you will have an even + odd, which is odd. 30 is an even number, but your result will be odd, no matter what 7 odd numbers you choose.
Why do all non square numbers have even factors?
The factors of all numbers can be written in pairs. With square numbers, one of those pairs is the same number twice. When listed singly, square numbers have an odd number of factors. All others are even.
Why do all numbers other than square numbers have even factors?
All numbers can be broken down into factor pairs. No matter how many pairs there are, it's an even number of factors. Squares have a factor pair that consists of the same number twice. When you list them, you list the number once.
What are the other pairs of adjacent primes than two and three?
No, because every other even number besides 2 is composite and odd numbers are never adjacent.
Why do all numbers other than square numbers have an even number of factors?
Factors come in pairs. It is only in the case of a square number that the two middle factors are equal and so are counted only once.

Multiplying an even number of negative numbers results in a positive number. This is because each pair of negative numbers multiplies to give a positive product, and with an even count, all pairs will cancel out the negativity. Therefore, the final result will be positive.
The set of even prime numbers?
There is only one even prime number, which is 2. Every other even numbers is divisible by 2, as well as by 1 and itself, so no other even number can be a prime number. Thus, the entire set of even prime numbers is the number 2.
How many pairs of even numbers can you find whose sum is eighteen?
2 + 164 + 146 + 128 + 104 pairs of even numbers can be found whose sum is eighteen.
Which of the first ten prime numbers are even numbers?
There is only 1 even prime number which is 2

5+5+5+5+1 That is only 5 numbers being added. There can be no answer for six numbers for the following reasons: The numbers are all odd. Two odd numbers make an even number. Two even numbers make an even number. 21 is odd. Take 6 odd numbers and add them up in pairs. Each pair of odd numbers gives an even number so there are 3 even numbers. Even + Even + Even = Even. So sum of any six odd numbers is even but 21 is not even.
What are the 2 prime numbers that equal 48?
There are no two prime numbers that add up to 48. The only even prime number is 2, and if we pair it with another prime number to equal 48, the second number would be 46, which is not prime. All other pairs of prime numbers will yield odd sums, making it impossible to find two primes that sum to an even number like 48.
