Why is odd times odd numbers always odd numbers?
In the same way that and odd plus and even is always odd. For example, 7*3 = (7+7) odd + odd = even , then add +7, apply rule that odd + even = odd and get that it equals 21.
If the sum of two numbers is even then the two numbers must be even?
If the sum of two numbers is even, the two numbers are either both even or both odd. A few examples:2 + 4 = 6 (even + even = even)2 + 3 = 5 (even + odd = odd)5 + 2 = 7 (odd + even = odd)7+13 = 20 (odd + odd = 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.
When does an even number of odd numbers equal an odd number?
Never. When you dont add the same odd number and even number of times. For example: 5 + 3 (2 odd numbers; and even amount of odd numbers ) = 8 5 + 3 + 7 = 15 an odd amount of odd numbers 5 + 3 + 7 + 9 = 24 another even amount of odd numbers. But never if you use the only same number
If the product of 2 even numbers is even then the 2 numbers must be even?
This is not always true. If the sum of two numbers is even, then those two numbers are either both even or both odd. For example: 2 + 2 = 4 (even + even = even) 5 + 7 = 12 (odd + odd = even) 3 + 2 = 5 (odd + even = odd)
Are 7 and 8 odd numbers?
The number 7 is not divisible by 2, so it is odd. The number 8 is divisible by 2, just as all even numbers are. It is an even number.
How can you determine whether the sum of several numbers such as 13 45 24 17 is even or odd without actually calculating the sum?
Just add the end numbers, so 3 + 5 + 4 + 7 = 19 which is odd. Alternatively, ignore even numbers [such as 4], and two odd numbers [3 and 5] added always make an even number [8], which leaves and odd number [7] so the answer will be odd. Example; five hundred different numbers, where 483 are even and 17 are odd, then no matter what the actual 500 numbers are the answer will be odd, as there is an odd [17] quantity of odd numbers.
What 3 consecutive odd numbers total 270?
Since 270 is an even number, then three consecutive odd numbers cannot add to 270. ,because Odd + odd = even (2 numbers_ Even + odd = odd ( plus a third number) odd + odd = even (plus a fourth number) even + odd = odd (plus a fifth number) Notice from the table that the third odd number gives an odd answer; not an even answer. e.g. three odd numbers 3,5, & 7. 3 + 5 = 8 (even) 8 + 7 = 15 ( odd) et. seq.,
Is 121 even or odd?
It's an odd number. Even numbers, when divided by two will always give the answer as a whole number. Odd numbers do not. Numbers ending in 0, 2, 4, 6, 8 are even, and numbers ending in 1, 3, 5, 7 or 9 are odd.
Can 5 odd numbers that if you add them make 32?
37
What the pattern called even odd numbers?
There is no such pattern because there are no even odd numbers. Odd numbers, by definition, are odd and therefore, not even.
What are even and odd numbers?
Simply put, even numbers are numbers divisible by two. Odd numbers cannot be divided by two. This has to do with dividing an integer by two. If there is no remainder, the number is said to be even; if there is a remainder of 1, the number is said to be odd. Even numbers end with 0, 2, 4, 6, or 8. Odd numbers end with 1, 3, 5, 7, or 9.
