00:00:01.823 --> 00:00:03.003
Do your homework!
2
00:00:03.123 --> 00:00:05.807
I don't know how to do a numerical expression.
3
00:00:05.923 --> 00:00:08.300
Oh, I am sorry i didn't know that.
4
00:00:08.302 --> 00:00:09.820
Ask your teacher tomorrow.
5
00:00:10.925 --> 00:00:13.489
Ok, hopefully I won't get in trouble.
6
00:00:15.606 --> 00:00:19.097
I heard you have been having trouble with numerical expression.
7
00:00:19.206 --> 00:00:21.661
Yes, it's hard, I don't get it.
8
00:00:21.787 --> 00:00:25.255
Oh, it's easy, all you have to remember is P.
9
00:00:25.555 --> 00:00:25.409
E.
10
00:00:25.709 --> 00:00:25.563
M.
11
00:00:25.863 --> 00:00:25.717
D.
12
00:00:26.017 --> 00:00:25.871
A.
13
00:00:26.171 --> 00:00:26.025
S.
14
00:00:26.154 --> 00:00:27.294
What does that mean.
15
00:00:28.421 --> 00:00:31.248
It means pleas excuse my dear aunt Sally.
16
00:00:31.372 --> 00:00:37.563
It also means parentheses,exponents,multiply,divide,add,subtract.
17
00:00:37.677 --> 00:00:39.229
When do you do those steps?
18
00:00:40.338 --> 00:00:45.631
Let's say you have a problem of 2 minus(35 plus 7 minus 20 plus 5)
19
00:00:45.658 --> 00:00:53.559
In the problem (35 plus 7 minus 20 plus 5)minus 2 you do 35 plus 7 first since it's in the parentheses.
20
00:00:53.572 --> 00:00:56.513
Can you tell me what's 35 plus 7 Kris.
21
00:00:56.709 --> 00:00:57.939
It is 42.
22
00:00:58.055 --> 00:00:58.875
Good job.
23
00:00:59.175 --> 00:01:01.243
Now, what do you do next.
24
00:01:01.359 --> 00:01:03.107
Then you do 20 plus 5.
25
00:01:03.622 --> 00:01:05.024
The answer is 25.
26
00:01:05.324 --> 00:01:06.179
I get it now.
27
00:01:06.479 --> 00:01:11.787
Then you do 42 minus 35 since that is the answer to the 2 problems.
28
00:01:11.905 --> 00:01:14.172
Wonderful, you are doing great honey.
29
00:01:14.273 --> 00:01:17.476
The answer to 42 minus 35 is 7.
30
00:01:17.588 --> 00:01:23.387
Then since you finished the parentheses you do what's outside of the parentheses which is minus 2.
31
00:01:23.687 --> 00:01:25.161
so what is your final answer.
32
00:01:25.293 --> 00:01:26.058
5.
33
00:01:27.089 --> 00:01:30.893
Thank you, now I know how to do the numerical expressions.
34
00:01:31.022 --> 00:01:35.795
Remember if you have exponents,that then do multiplication, then division.
35
00:01:36.095 --> 00:01:38.182
then add and subtract in that order.
