If X and Y are sets of integers, X # Y denotes the set of integers that belong to set X or set Y, but not both. If X consists of 16 integers, Y consists of 18 integers, and 6 of the integers are in both X and Y, then X # Y consists of how many integers?  Pick one
A) 6  B) 16  C) 22  D) 30  E) 174
The number of integers that belong to set X ONLY is 16-6= 
<gadget id="calculator">16-6</gadget>

10;   The number of integers that belong to set Y ONLY is   18-6= 
<gadget id="calculator">  18-6</gadget>
<output>12</output>
12;   The number of integers that belong to set X or set Y, but not both is   10+12= 
<gadget id="calculator">  10+12</gadget>
<output>22</output>
22.   Answer: 22
