If the set including elements three, five, and one is equal to the set of elements one, three, and đť‘Ą, what is the value of đť‘Ą?
00:00:11.270 --> 00:00:17.340
Now it may seem like the first numbers go together, the second numbers go together, and the third numbers go together.
00:00:17.340 --> 00:00:26.790
But that is not right, not correct, and hereâ€™s why. when we have a set, the order that we write the elements actually doesnâ€™t matter.
00:00:27.240 --> 00:00:35.510
So if we wanted to, we could write instead of three, five, one, we could write five, three, one or one, three, five.
00:00:35.670 --> 00:00:36.510
It doesnâ€™t matter.
00:00:36.970 --> 00:00:39.560
So letâ€™s compare the sets.
00:00:40.030 --> 00:00:45.100
This first set letâ€™s call it A, and the second set we will call B.
00:00:45.540 --> 00:00:49.610
So set A has numbers three, five, and one.
00:00:50.190 --> 00:00:53.840
Set B has numbers one, three, and đť‘Ą.
00:00:54.290 --> 00:01:01.200
So letâ€™s see what matches up, because if the sets are equal, they should have the exact same elements in them.
00:01:01.740 --> 00:01:04.480
So A and B both have element three.
00:01:05.100 --> 00:01:07.160
They both have element one.
00:01:07.680 --> 00:01:11.740
And all thatâ€™s left that has to match is five and đť‘Ą.
00:01:12.340 --> 00:01:14.840
Therefore, đť‘Ą must be equal to five.
