The sum of two numbers is a whole number if both of the numbers are whole numbers, or if the sum of two fractions can be simplified to a whole number.

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
The sum of whole numbers from 1 to 50 can be calculated using the formula for the sum of an arithmetic series: ( S = \frac{n(n + 1)}{2} ), where ( n ) is the last number in the series. Here, ( n = 50 ), so the sum is ( S = \frac{50(50 + 1)}{2} = \frac{50 \times 51}{2} = 1275 ). Therefore, the sum of whole numbers from 1 to 50 is 1,275.
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.

2 mixed numbers can only be a whole when the 2 numerators add up to the number
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.
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

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 '.
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 whole numbers from 1 to 50 can be calculated using the formula for the sum of an arithmetic series: ( S = \frac{n(n + 1)}{2} ), where ( n ) is the last number in the series. Here, ( n = 50 ), so the sum is ( S = \frac{50(50 + 1)}{2} = \frac{50 \times 51}{2} = 1275 ). Therefore, the sum of whole numbers from 1 to 50 is 1,275.
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.
