Any two odd numbers will have an odd product and an even sum.
Which pair of numbers has an even product and an odd sum?
Any pair of one even and one odd number will have an even product and an odd sum.
How could you determine whether a sum of numbers such as 127 plus 38 is even or odd?
The parity rules are: Odd + Odd = Even Even + Even = Even Odd + Even = Odd Even + Odd = Odd So the parity where one number is even is that of the other number. This means that you can go through a list of numbers and ignore all the even numbers. Every PAIR of odd numbers has even parity and by the previous paragraph, even parity can be ignored. So you can pair off odd numbers and ignore them.
Is there an even numbers between every pair of consecutive odd numbers?
yes
How do you write an odd number with even numbers?
If you add, subtract, or multiply two even numbers, you will get an even number. If you divide an even number by another even number, you may get an even number, an odd number, or even a fraction.
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.
How are the sum and product of each pair of numbers related?
They have the same parity (odd or even).
What do you get if you subtract an odd and even number?
Odd. First subtract 1 less than your odd number, (which is obviously even) to get even - even, which is even. Then take off your spare 1 to finish up odd.
what happen if you subtract three odd numbers?
you get an odd number
How do you know that 2 and 3 are the only conseqtive prime numbers?
