How many pairs of whole numbers have the sum of 10

5

Step-by-step explanation:

Just do it like this:

1 and 9

2 and 8

3 and 7

4 and 6

5 and 5

11

Step-by-step explanation:

Whole numbers are all those numbers that are zero or greater then zero, so:

{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, }

The list of the pairs is the following:

(0, 10)

(1, 9)

(2, 8)

(3, 7)

(4, 6)

(5, 5)

(6, 4)

(7, 3)

(8, 2)

(9, 1)

(10, 0)

Two pairs with the same numbers, but in different position are not the same thing. They are two different pairs.

For example, (2, 8) and (8, 2) are different. You can imagine them as points on a Cartesian coordinate system to understand why they are different. They are two different points.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
