To make the list of two-digit numbers with digits that add up to 10, first write the pairs of single-digit integers that add up to 10. They are (1,9), (2,8), (3,7), (4,6), (5,5). Then recognize that each of these pairs of numbers, except 5, can be combined in two different ways to make two-digit numbers that satisfy the problem. 19 and 91 28 and 82 37 and 73 46 and 64 55 So there are nine two-digit numbers with digits that add up to 10.
You add the two numbers and then divide it by two. It basically doing the mean which is adding all the numbers and dividing it by how many numbers there are. I hope this helped!

You must add either two odd numbers or two even numbers.
5 different ways isn't it
With whole numbers, there are five ways.
If you want to add two numbers and get 775, there are 194 different ways to do it IF you onlyuse positive whole numbers ... a lot more than that if you're allowed to use negative numbersand fractions.If you want to add three numbers and get 775, there are even more ways to do it.
Its indefinite: Start with 0,1 add last two numbers = 1 add to sequence = 0,1,1 add last two numbers = 2 add to sequence = 0,1,1,2 add last two numbers = 3 add to sequence = 0,1,1,2,3 add last two numbers = 5 add to sequence = 0,1,1,2,3,5 add last two numbers ......... add to sequence ..........

Add two numbers.

Many ways, but the simplest is add the two numbers together and divide the answer by 2. For example, number between 23 and 42. Add them together: 23 + 42 = 65 Divide by 2: 65/2 = 32.5 So 32.5 is [exactly halfway] between 23 and 42.
5.5 is the median when your two numbers are 1 and 10. There are two ways of getting it. Add both numbers and divide by 2 or find the number half way between the two.
NO mean: (average)add all the numbers, then divide by how many numbers you added!! Median: you have to put allthe numbers in order and then get the middle number and if there are two middle numbers add them and divide them by two!!
Add the two numbers and divide that by two.
