A X B. what does that mean? you mean A*B?

The intersection or union.

ledah · Answer

hm. alright. so what steps would you take to find A X B?

jim_thompson5910 · Answer

Similar example: 

If A = {6,7} and B = {8,9,10} 

then 

A X B = {(6,8),(6,9),(6,10),(7,8),(7,9),(7,10)}


You basically form ordered pairs where the first coordinate comes from set A and the second coordinate comes from set B
