What adds up to 100?

Answer 1

There are an infinite number of answers:

1 + 99, 1 + 1 + 98, 1 + 1 + 1 + 97 etc,

2 + 98, 2 + 1 + 97, 2 + 2 + 96 etc,

then

(-1) + 101, (-1) + (-1) + 102, (-1) + (-1) + (-1) + 103, etc

But not forgetting fractions:

0.1 + 99.9, 0.2 + 99.8, and

0.01 + 99.99, 0.02 + 99.98 etc

Nor the surds

[1+sqrt(2)] + [99-sqrt(2)]

etc.
