Question

I don't get what there asking two natural numbers have a sum of 23?

Answer 1

I think the answer has to be 11 and 12.  They are the only two natural numbers (the integers, i.e., not fractions) that when added together give you 23.

Answer 2

You don't get what there (where?) asking two natural numbers have a sum of 23?

There are 23 sets of 'two natural numbers that have a sum of 23'.

They are:

1 + 22 = 23

2 + 21 = 23

3 + 20 = 23

4 + 19 = 23

5 + 18 = 23

6 + 17 = 23

7 + 16 = 23

8 + 15 = 23

9 + 14 = 23

10 + 13 = 23

11 + 12 = 23

12 + 11 = 23

13 + 10 = 23

14 + 9 = 23

15 + 8 = 23

16 + 7 = 23

17 + 6 = 23

18 + 5 = 23

19 + 4 = 23

20 + 3 = 23

21 + 2 = 23

22 + 1 = 23

Answer 3

12 and 11 would be examples of this.

Both natural numbers that sum up to 23.
