What two numbers added together equals 57?

Answer 1

There are an infinite number of possible answers:

1 and 56, 2 and 55, 3 and 54, etc

then -1 and 58, -2 and 59, -3 and 60, etc.

Between them theres an infinite number.

Then bring in the 1-digit decimals:

1.1 and 55.9, 1.2 and 55.8, 1.3 and 55.7, etc

and the 2-digit decimals:

1.01 and 55.99, 1.02 and 55.98, etc

and 3-digit, 4-digit etc decimals.

Then start with the irrationals:

1+sqrt(2) and 56-sqrt(2), etc

And, if you are really serious about it, bring in complex numbers as well:

1+i and 56-i, 2+i, 55-i, etc
