The short notation of this would be 12C2
There are 12 possible selections for the first person, and 11 possible selections for the second person. 12x11 is 132
But half of these options are the same as another option but with the people being picked the other way around, so for the real value we need to do 132/2 or 66.
Thus, there are 66 ways a committee of 2 can be selected from a club with 12 members.
66 because 12 for the first person and 11 for the second
12 x 11 = 132
Half of these options are the same
132 / 2 = 66

53,130 ways.
You calculate this as 1010 over 66 - that is:(1010 x 1009 x 1008 x 1007 x ...) / (1 x 2 x 3 x 4 x ...) with a total of 66 numbers at the top and at the bottom. Excel can help you with the actual calculations.
