What number add up to 14?

Answer 1

There are infinitely many ways.

Think of any number, say x.

calculate y = 14 - x

Then x + y = 14

Since the choice of x was arbitrary, there are infinitely many answers.

That applies to pairs of numbers. You can repeat the process for sums of 3, 4, ... numbers.

Also, you can look at multiplication and other ways of combining numbers (binary operations).

Answer 2

7+7=14
