We need to simplify the following.
00:02
So we're going to do our division first.
00:04
So 40 divided by 2 is 20.
00:08
And then we have times 4 plus 6.
00:11
So that becomes 80 plus 6, which is 86.
00:15
Then we have 15 minus 6, which is 9 plus 4 minus 1, which is 3 times 24.
00:25
So we subtract, or no, we at multiply 3 times 24.
00:30
And then you add nine, and that's equal to 81.
00:35
Then the next one, we multiply.
00:36
So we have 60 plus 45.
00:42
So that's 105.
00:44
Then the next one, we have three times, we do three plus two times.
00:52
We do our parentheses, which is seven.
00:55
And this becomes 14.
00:57
Then we do 14 times 3, which becomes 17.
01:02
So 3 times 17 is 51.
01:06
Our next one, we have 12 plus 3 times in parentheses 4 plus.
01:11
We do the inside parentheses, which is 1 minus 2.
01:15
Then we do 4 plus 1, which is 5 minus 2 is 3.
01:20
We multiply, so that's 12 plus 9.
01:24
So that's 21...
