How do you find the sum of the number 70?

Answer 1

There are an infinite number of possibilities:

1 + 69, 2 + 68, 3 + 67, etc

or

1.1 + 68.9, 1.2 + 68.8, 1.3 + 68.7, etc

or

2.1 + 67.9, 2.2 + 67.8, etc

or

71 - 1, 72 - 2, 73 - 3, etc

or

71.1 - 1.1, 71.2 - 1.2, etc

or

72.1 - 2.1, 72.2 - 2.2, etc

and not to forget multiplications and divisions.

And then there are Irrational Numbers, and complex numbers.
