1. When all members of the United States Senate meet, there are one hundred members present.

One day, the 8 Republicans on the judiciary committee met together while the 8 Democrats met with the remaining members of the Senate.
84 + 8 Dems in big room , 8 Repubs in other
(84+8) + 8 = 100

The next day, the entire judiciary committee met together while the rest of the Senate met.
84 + room with 8 dems and 8 repubs = 100
84 +(8+8) = 100
So
84 + (8 + 8) = (84 +8) + 8
That is the Associate Property
a + (b+c) = (a+b) + c

The total number of senators remains at 100.
100 = 84 + 16
