### 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…

### 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…

### Between 1 and 100 how many multiples of 7 are odd numbers?

Start out looking at them. 7x1=7 odd 7x2=14 even 7x3=21 odd 7x4=28 even 7x5=35 odd 7x6=42 even... so it looks like half might be even and half odd, This is because if we look at the numbers 1-14, ie 1,2,3,4,5,6,7,8,9,10,11,12,13. and 14, they alternate odd and even and since 7 is odd and odd times an even is always an even number and an odd times an odd is always an odd number. So to…

### What is odd integers?

Odd integers are whole numbers that are not evenly divisible by 2. If you count, starting at 1, you will have alternating odd and even numbers. 1 is odd, 2 is even, 3 is odd, 4 is even, 5 is odd, 6 is even, 7 is odd, and so forth to infinity. Negative numbers have the same property (minus one is also odd, etc.) and zero is also an even number.

### Can 5 odd numbers that if you add them make 32?

No. The sum of two odd numbers or two even numbers is an even number. The sum of an even number and an odd number is an odd number. The sum of 5 odd numbers is: ((odd + odd) + (odd + odd)) + odd = (even + even) + odd = even + odd = odd But 32 is an even number, therefore it cannot be the sum of 5 odd numbers.

### What are even numbers 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.

### Are prime numbers same as odd numbers?

No. Prime numbers are numbers that can only be divided evenly by itself and 1. For example, the number 7 can only be divided by 7 and 1. Odd numbers are numbers that end in (or are) 1, 3, 5, 7, or 9. For example, the number 21 is odd since it ends in a 1, but it is not prime because it can be divided by 1, 21, 7, and 3. (7 times 3…

### What is the pattern of odd and even numbers in the row 3 or 3 column?

Alternating. 1 2 3 4 5 6 7 8 9 in row 3, (7,8,9) the 8 is even and the 7 and 9 are odd. thus odd,even,odd. in column 3, (3,6,9) the 6 is even and the 3 and 9 are odd, thus odd,even,odd. as the row/column selector (3) is odd the first digit in that row/column of a 3X3 grid will be odd as will the first. the numbers then alternate even odd even.

### Why aren't all odd numbers divisible by 3?

Because not all odd numbers are multiples of 3 - I have shown you below that this is the case and you can see some multiples of 3 are even and some are odd and you can also see that there are even and odd numbers BETWEEN the multiples of 3. 1 (odd) 2 (even) 1*3 =3 (odd) 4 (even) 5 (odd) 2*3 = 6 (even) 7 (odd) 8 (even) 3*3 = 9 (odd) 10…

### When multiplying an odd number by an odd number why is the result odd?

The product of multiplication results in a number that has all of the factors of the two numbers being multiplied. All even numbers have the prime factor 2. Since no odd number has the factor 2, no product of those numbers can have it. So: - Odd numbers times odd numbers produce odd numbers. - Odd numbers times even numbers produce even numbers. - Even numbers times even numbers produce even numbers.
