Calculating these.
00:01
So i'll do a couple of them really quick.
00:04
So two to the third power means two times two times two, which is eight.
00:08
A negative four plus two is a negative two.
00:11
A negative 11 and a negative three is a negative 14 because same signs add and keep.
00:16
A negative two times a negative five is a positive 10 because when multiplying same signs, the answer is going to be positive.
00:28
A one -third to the fifth power would be one over, let's see, three to the fifth power is, one over 243 because that's one -third times one -third times one -third times one -third, times one -third.
00:44
Negative four divided by a negative eight is a positive one -half because four -eight is one -half and a negative divided by a negative is a positive.
00:56
Negative 3 raised to the fourth power is a positive 81.
01:03
And then 3 4ths times 1 4th is 3 .16s.
01:11
Let's see, 2 thirds plus 3 .5ths, common denominator of 15.
01:20
So 9, 10.
01:23
So that would be 19 over 15, which equals 1...
