00:00:04,819 --> 00:00:07,060
Hey, everyone, Alena here.

3
00:00:07,060 --> 00:00:10,810
Practice is vital to becoming
a proficient developer.

4
00:00:10,810 --> 00:00:14,870
It solidifies what you've learned,
causing it to stick in your memory.

5
00:00:14,870 --> 00:00:17,480
With deliberate practice,
it becomes quicker and

6
00:00:17,480 --> 00:00:21,370
easier to solve the challenges
you'll face everyday.

7
00:00:21,370 --> 00:00:22,760
So let's practice some PHP.

8
00:00:24,020 --> 00:00:26,810
This session covers creating
number variables and

9
00:00:26,810 --> 00:00:29,630
applying some mathematical operations.

10
00:00:29,630 --> 00:00:33,220
This practice session is intended
to follow the second stage

11
00:00:33,220 --> 00:00:35,490
of the PHP basic course.

12
00:00:35,490 --> 00:00:37,870
If you haven't taken
that course already or

13
00:00:37,870 --> 00:00:40,590
find this practice session to difficult.

14
00:00:40,590 --> 00:00:45,220
Then review stage two of
the PHP basics course first.

15
00:00:45,220 --> 00:00:50,300
Check the notes associated with this
video for additional links and resources.

16
00:00:50,300 --> 00:00:52,200
Let's review the challenge.

17
00:00:52,200 --> 00:00:54,430
There are seven step to
completing this challenge.

18
00:00:55,440 --> 00:00:57,790
The file includes the comment for
each step.

19
00:00:58,910 --> 00:01:00,770
Add your code below each comment.

20
00:01:01,900 --> 00:01:03,160
Step one.

21
00:01:03,160 --> 00:01:08,080
Create a variable named Ours and
set it to the integer value of 40.

22
00:01:08,080 --> 00:01:10,970
Step two.

23
00:01:10,970 --> 00:01:16,634
Create a variable named Productivity and
set it to the float value of 10.5.

24
00:01:17,648 --> 00:01:21,740
Step three, create a third
variable named first total and

25
00:01:21,740 --> 00:01:26,360
then set it equal to the value of
multiplying hours by productivity.

26
00:01:27,770 --> 00:01:31,140
Step four, add 1 to the Ours variable.

27
00:01:32,160 --> 00:01:36,820
Step five, subtract 0.5 from
the productivity variable.

28
00:01:38,180 --> 00:01:42,280
Step six, create a third
variable named secondTotal and

29
00:01:42,280 --> 00:01:46,200
set it equal to the new value of
multiplying hours by productivity.

30
00:01:47,370 --> 00:01:52,040
Step seven,
replace the comments to add firstTotal and

31
00:01:52,040 --> 00:01:54,150
secondTotal to the following output.

32
00:01:55,280 --> 00:02:00,249
At any point to test out what you've done,

33
00:02:00,249 --> 00:02:06,194
go to View, Show Console and
type php index.php.

34
00:02:11,748 --> 00:02:15,960
It's okay to make multiple attempts
before coming to a solution.

35
00:02:15,960 --> 00:02:18,370
That struggle to remember
what you've learned and

36
00:02:18,370 --> 00:02:22,800
apply it to the situation is what
causes the knowledge to take root.

37
00:02:22,800 --> 00:02:24,370
If you do get stuck,

38
00:02:24,370 --> 00:02:28,950
I've included additional resources in
the notes associated with this video.

39
00:02:28,950 --> 00:02:30,320
Go ahead and give it a try.

40
00:02:30,320 --> 00:02:32,650
And I'll show you my
solution in the next video.
