## How do you find the sum or difference?

Add and subtract the remaining numbers in the math problem. The sum will be the result of adding numbers, while the difference will be the result of subtracting them. For instance, in the math problem 4 + 3 – 5, the sum of 4 and 3 will be 7, and the difference between 7 and 5 will be 2.

## How do you calculate a sum?

Take the sum of all the values in your data set, then divide that by the total number of values. Example: for the values 2, 4 and 9, the sum is 15, which, divided by 3, gives a mean average of 5.

## What is the sum of 15?

The possible number whose combination would result in sum of 15 are: 69, 78, 87, 96. So, there are only 4 combinations which would result in 15.

## What is the sum of two numbers is 11 and their difference is 3?

When you have a sum and a difference and add them together, that is the same as doubling one of them. For example, if the two numbers are 7 and 4, then the sum is 11 and the difference is 3. When we add the sum and the difference together, we get 14, which is double the original 7.

## What two numbers add up to?

When two numbers are added together, the result is called a sum. The two numbers being added together are called addends.

## What is the sum of 8 and the difference of 2?

## What has a sum of 18 and a difference of 6?

“THE SUM OF two numbers is 18 and the difference is 6”. So x+y = 18 and x-y = 6. Algebraically, we can add those two equations to find 2x = 24, so x = 12.

## What is the sum of two numbers is 11 and their difference is 5?

Answer. Let the numbers be x & y. so the numbers are 8 and 3. If it helps please mark it brainliest.

## What is the sum of 18 and the difference of 2?

The numbers are 10 and 8. Their sum = 18 and the difference between them = 2. Add (1) and (2): 2a = 20 or a = 10, and so b = 18–10 = 8. The sum of 2 numbers is 18 and the product of the same 2 numbers is 84.

## What is the sum of the number from 1 to 10?

The number series 1, 2, 3, 4, . . . . , 9, 10. Therefore, 55 is the sum of positive integers upto 10.

## What two numbers have a sum of 20 and a difference of 4?

And since their sum is -4, the negative number is 4 units farther from zero than the positive number, and the sum of their distances from zero is 20. So, we can ask ourselves, what two numbers add up to 20 whose difference is 4. It should be easy to see we need 12 and 8. So the two numbers we need are -12 and 8.
