Answer 2

The upside-down U symbol stands for an intersection. An intersection of two sets is all of the elements that both sets share and none others. In your exercise with A={1,2,3,4,5} and B={2,4,6,8}, the only elements that A and B both share are {2,4}. Thus, your intersection will be those elements.

Answer 4

Natural numbers are whole, non-negative numbers, including 0. For example, 8, 10, and 12 are all natural numbers, but -4 and 3/5 are not. What you are looking for for P are all of the natural numbers that are less than 6. Therefore, what will P be?

Answer 5

12345?

Answer 6

Almost! The natural numbers include 0 too. So, add that to the set you have there and you will be good to go!

Answer 7

Factors of a number are all of the numbers that that number can be divided by with no remainder resulting from the division. For example: for 6, the factors of 6 are 1,2,3, and 6. Thus, for this one, you are looking for all of the numbers that 12 can be divided by that will result in a whole number. What will those be? Hint: there are six of them.
