SOLUTION: List the numbers in set F that are natural, integers, rational, irrational and real.
F = {-sqrt{2}, pi + sqrt{2}, (1/2) + 10.3}
Natural = none
Integers = none

In your post, you say "Irrational = every element in set F".
It is not correct. Element (1/2) + 10.3 of F is a rational number.
So, it should be fixed.
The other answers are correct.
