Question 8

For (a), rational, integer, natural
For (b), rational
 
Question 8
where do you see a and b

8. (3-sqrt(2)) +(3+sqrt(2)=3-sqrt(2) +3+sqrt(2)=6 ->natural, integer, rational

For 8, there is no (a) and (b). It is a typo. Keep in mind that I am working now. It's easy to make mistakes when doing too many things at once. The building is empty as most employees left for the long holiday weekend. So, why not do some math?

For 10, I say rational. Yes?
