You know that sum of the first n whole numbers is n(n+1)/2. ( it is the same as the first n natural numbers since the zero does not add anything) So lets say you want the sum of all the whole numbers between 3 and 10. ( I made it easy to illustrate the idea.) The sum of the whole numbers between 0 and 3 is 3(4)/2=6 The sum of the whole numbers between 0 and 10 is 10(11)/2=55 So the sum of the whole numbers between 3 and 10 is the (sum of the whole number between 0 and 10) -(sum of whole numbers between 0 and 3) which is 55-6=49 So in general, for whole numbers m and n with m
1+ 1and 1/2
Odd. For any given whole number n, the sum of it and the next whole number is 2n+1. Since 2n is obviously a multiple of 2 and therefore even, 2n+1 must be odd.
The sum is 150*151/2 = 11,325

2 mixed numbers can only be a whole when the 2 numerators add up to the number
No. Each mixed number is made of a whole number and a fraction. When you add them, you have the sum of two whole numbers and two fractions. Since each whole number must be at least ' 1 ', the sum of two whole numbers must be at least ' 2 ', and the two fractions will always make it more than ' 2 '.
No. -2 and -3 are both whole number and their sum is -5 which is smaller than both.
The three consecutive whole numbers you are looking for are 1, 2, and 3. The sum of the first two numbers, 1 + 2 = 3.

Oh, isn't that a happy little question. Let's say we have the mixed numbers 2 1/2 and 1 1/2. When we add them together, we get a sum of 4, which is a lovely whole number. Just like that, we've created a beautiful harmony on our canvas of numbers.

The sum of two prime numbers greater than 2 is an even number. The sum of 2 and any other prime number is an odd number.
the sum of two whole numbers is always greater than either addend* * * * *No.Consider:5 is a whole number-3 is a whole number.Their sum is 2, which is notgreater than one of the addends (5).
The sum of the first thousand whole numbers can be calculated using the formula for the sum of an arithmetic series, which is n/2 * (first term + last term), where n is the number of terms. In this case, the first term is 1 and the last term is 1000. So, the sum would be 1000/2 * (1 + 1000) = 500 * 1001 = 500500.
Odd. For any given whole number n, the sum of it and the next whole number is 2n+1. Since 2n is obviously a multiple of 2 and therefore even, 2n+1 must be odd.
