hey there mathematicians it's cool

2
0:00:07,839 --> 0:00:09,910
school and i'm your math science and

3
0:00:09,920 --> 0:00:11,990
english teacher professor science and

4
0:00:12,000 --> 0:00:13,749
this is math class

5
0:00:13,759 --> 0:00:15,589
let's get going

6
0:00:15,599 --> 0:00:17,990
if you have nine otters floating in a

7
0:00:18,000 --> 0:00:20,320
river

8
0:00:23,680 --> 0:00:26,150
and you take away five because they

9
0:00:26,160 --> 0:00:30,279
float off a waterfall

10
0:00:30,560 --> 0:00:33,030
how many do you have left

11
0:00:33,040 --> 0:00:35,510
click on the correct answer

12
0:00:35,520 --> 0:00:36,549
are there

13
0:00:36,559 --> 0:00:38,950
six otters left

14
0:00:38,960 --> 0:00:41,270
five otters

15
0:00:41,280 --> 0:00:44,549
are there only two otters left

16
0:00:44,559 --> 0:00:47,920
or are there four hours left

17
0:00:54,800 --> 0:00:55,990
nope

18
0:00:56,000 --> 0:00:59,239
try again

19
0:01:04,479 --> 0:01:06,230
that's not it

20
0:01:06,240 --> 0:01:07,910
remember

21
0:01:07,920 --> 0:01:10,149
there were nine otters

22
0:01:10,159 --> 0:01:14,469
and five of them fell off the waterfall

23
0:01:14,479 --> 0:01:16,960
try again

24
0:01:22,320 --> 0:01:23,429
yes

25
0:01:23,439 --> 0:01:25,670
there are four otters

26
0:01:25,680 --> 0:01:27,429
nine minus five

27
0:01:27,439 --> 0:01:29,270
is four

28
0:01:29,280 --> 0:01:31,030
now i ask you

29
0:01:31,040 --> 0:01:32,390
what happened to the otters that fell

30
0:01:32,400 --> 0:01:35,200
off the waterfall

31
0:01:35,520 --> 0:01:38,079
the answer

32
0:01:38,840 --> 0:01:42,789
nothing just pictures after all
