Okay, so this wants you to estimate each product and then compute the actual product.
00:06
So i'm going to do 0 .4 times 40.
00:13
So that's going to be, you should get about, come on, you should get about 1 .6.
00:28
So then i have 2 times 5 is 10, then 6, add a happy 0, 20, 14.
00:37
So 14 .60, that's a 14 .60 is my answer.
00:43
0 .5 and 0 .6, so i should get 3 .0.
00:51
So i have 9 times 4, which is 36, 3, 48, 0, 20, 25, so 27.
01:05
So then i have 6, 8, 11, 31, 3 .186.
01:16
Oh, 0.
01:17
I had my decimal in the wrong spot.
01:19
Sorry about that, 0 .3186.
01:23
This one is, i would do 0 .8 times 6.
01:30
So that would be 4, 0.
01:35
Oops, got that in the wrong spot.
01:39
0 .8 times 6 is 4 .8.
01:47
And then 0 .75 times 6, that is 4 .5.
01:56
Then this is 5 .2 times 0 .5.
02:01
So 5 .2 times 0 .5 is 2 .6.
02:07
And then 5 .28 times 8, that is 44 ,224.
02:21
And then add my happy 0, and then 2, 3, 8, 11, and the 1, 21.
02:30
So then that is 4, 4, 3, 5, 2.
02:38
And then that's 2 .5, 3, 4, 4, 0 .6, 0 .4.
02:46
That's 0 .24.
02:53
And then i have 0 .63 times 9.
02:58
That's 5, 6, 7.
03:01
And then i have my happy 0, 9, 18, 7, 15, 14.
03:10
And add, that's 0 .2457.
03:15
So i have 60 and 0 .4.
03:20
So that's 2 .4...
