What numbers add up to 23?

Answer 1

There are infinitely many solutions.

... , -2 + 25, -1 + 24, 0 + 23, 1 +22, 2 + 21, ...

and

... , -2 - 1 + 26, -2 + 0 + 25, -2 + 1 + 24, ... , -1 - 1 + 25, -1 + 0 + 24, ... and infinitely many other triplets,

and quadruplets etc.

and then there are decimals to 1 place,

and decimals to 2 places,

etc,

and infinitely recurring decimals.

Also you must not forget surds. In pairs, triplets, quadruplets, etc.

And finally, if you are really serious about it, there are also sets of complex numbers.
