We need to complete the following.
00:02
So the first one, we're going to add 16 plus 23.
00:08
So that's 39.
00:09
So that's letter b.
00:11
Then we're going to find the sum of negative 68 and negative 45.
00:16
So we add those.
00:16
So that's 13.
00:18
That's 11, but it's negative.
00:21
So that's a.
00:22
We got negative 61 plus a positive 61 plus a negative 40.
00:29
So we're going to subtract.
00:30
So that's 21.
00:32
So that's d.
00:33
Then we're going to do the difference of negative 12 minus 4, a positive 4.
00:39
So that's going to equal negative 12 minus 4.
00:44
And that's equal to negative 16.
00:47
So that's a.
00:48
And then 64 decreased by negative 20.
00:52
That becomes plus plus.
00:54
So this is 84.
00:55
So that's c.
00:56
We're going to multiply 9 times 12...
