What numbers can make a total of 31?

Answer 1

There are infinitely many possible answers:

1+30

1+1+29

1+1+1+28

1+1+1+1+27 and so on

then

2+29

1+2+28

1+1+1+27 etc

and then introduce a 3, 4, and on and on.

Next, try numbers with one digit after the decimal point, and then 2 digits, 3, dits, ... infinitely many digits.

And you have not even started with negative number: 32+(-1), 33+(-1)+(-1), etc
