What happens if you add four numbers odd together?
You get an even number
What 5 odd numbers equal 30 when added and you can use the odd numbers more than once?
There are no 5 odd numbers that when added together make 30.Two odd numbers added together make an even numberAn odd number plus and even number makes an odd number.From the five odd numbers:Take two of them and add them together getting an even number and four odd numbersAdd another of the odd numbers to this even number and you will have three odd numbersAdd two of these together and you will have one even and one odd number.Finally add these odd and even numbers together and the result will be an odd numberBut 30 is an even number, so cannot be the sum of five (or any odd number of) odd numbers.
When odd number plus an even number is equal even numbers?
Any odd number can be written as an even number plus one. Any even number plus any other even number makes an even number. Add one makes an odd number. So an odd number plus an even number is always an odd number. Algebraically, any odd number can be written as 2a+ 1 where a is a whole number. Any even number can be written as 2b, where b is a whole number. Add them together, the sum is 2(a + b) + 1, which is odd.
When you add an odd and even number together is the sum odd or even and why?
The best way I can explain this is the way my kindergardenn teacher taught me. In even numbers, all the numbers will have a partner. With 2 each little person/number will have a partner. Now with an odd number, (such as three) there will be a person/number alone. so if you add an even and an odd there will be on little person without a partner, causing it to be an odd.
How can the sum of 3 odd numbers is always odd?
When you add an odd number to an odd number, you get an even number. When you add an odd number to that even number, the sum is always odd. Don't believe it? Try a few examples yourself.
