Venn Diagram.

I like examples because examples have me understand better such as

**25 + 16 = 41**

**41 - 32 =9**

**A = 25 - 9 = 16**

**B = 16 - 9 = 7**

**U = 13 - 7 = 6**

**or examples: **

**(a) 8 Juniors **

**(b) 8 seniors**

**(c) 8 seniors + 12 = 20 **

**(d) guards or centers **

**8 + 3 + 4 + 4 + 1 = 16 **

**(e) seniors who are not center or college students who are not guards**

**4 + 8 + 9 + 1 = 22**

**(f) junior high seniors who are are not centers **

**8 + 5 = 13 **
