Answer: No , it is not. RULE : WHENEVER TWO POSITIVE ODD DIGITS ARE ADDED OR SUBTRACTED, THE RESULT IS AN EVEN NUMBER.
What happens when you add three odd numbers?
When you add two odd numbers, it results in an even sum, and when you add three odd numbers it results in an odd sum.
Can you pick 3 watermelons to get a sum of 30?
Answer: 13,11,and 6 is answer.
Are numbers odd?
Odd numbers are whole numbers that cannot be divided exactly into pairs. Odd numbers, when divided by 2, leave a remainder of 1. 1, 3, 5, 7, 9, 11, 13, 15 … are sequential odd numbers. Odd numbers have the digits 1, 3, 5, 7 or 9 in their ones place.
Can sum of three odd numbers be even?
Without cheating, it’s not possible because sum of three odd numbers can’t be even. Let k be any real number.
What is odd number give example?
Any integer that cannot be divided exactly by 2 is an odd number. The last digit is 1, 3, 5, 7 or 9. Example: −3, 1, 7 and 35 are all odd numbers.
What happens when you add an even and odd number?
An odd number can only be formed by the sum of an odd and even number (odd + even = odd, or even + odd = odd). An even number can only be formed by multiplication in three ways: even·odd, odd·even, and even·even.
Why is the sum of an odd and even number odd?
When adding two of the addends together at a time, the answer rotates between even and odd. When the final two numbers are added together, one is even and the other odd. Therefore, the sum is odd, which makes the product odd since it is equivalent to the sum.
What is odd and even rule?
The Odd-Even rule is a space rationing scheme that determines which vehicles will ply on the roads on specific days. … Vehicles with registration numbers ending in odd numbers will be allowed on the roads on odd days and even-numbered vehicles will be allowed on the roads on even days.
How do you know if a number is odd?
To find an even number, look at the ones digit, or the digit to the very right of the number. (the ones digit in 5382 would be 2.) If the ones digit is either 0, 2, 4, 6, or 8, then the number is even. If the ones digit is either1, 3, 5, 7, or 9, then the number is odd.
What is the sum of even number?

What are odd numbers from 1 to 100?
A composite odd number is a positive odd integer which is formed by multiplying two smaller positive integers or multiplying the number with one. The composite odd numbers up to 100 are: 9, 15, 21, 25, 27, 33, 35, 39, 45, 49, 51, 55, 57, 63, 65, 69, 75, 77, 81, 85, 87, 91, 93, 95, 99.
Can you add two even numbers to get an odd number?
A simple rearranging of the terms above gives: 2n + 2m = 2(n + m). Therefore, any even number plus any other even number will always equal an even number (as the answer you get will always be some number multiplied by two). An odd number can be looked at as an even number with one added to it – e.g. 5 is 4+1.
How do you add odd numbers?
Proof of Sum of Odd NumbersSum of first odd number = 1.Sum of first two odd numbers = 1 + 3 = 4 (4 = 2 x 2).Sum of first three odd numbers = 1 + 3 + 5 = 9 (9 = 3 x 3).Sum of first four odd numbers = 1 + 3 + 5 + 7 = 16 (16 = 4 x 4).
Can you add 3 odd numbers to get 30?
We cannot get an even number (30) by adding three odd numbers by simple addition. In turn, we can take the factorial of an odd number which will help us to get the resultant 30 (even number).
