All language subtitles for 6. Exercise 14 Mathematical Functions

In this sectin
1

You have learnt mathematical functions
2

Let us test if you have learnt some of those functions
3

Suppose you are running a lottery for your customers and you want to pick out a list of Five Lucky customers
4

So use the random function in your customer table and get me a list of 5
5

Randomly picked customers
6

Small hint
7

To do this you need to order your result
8

With the random values and limit it to
9

5
10

In your second activity
11

Suppose
12

You cannot charge the customer
13

In decimal points
14

So if you have a sales value of 1.63
15

You can either charge the customer one
16

Or two units
17

In this scenario
18

You have three options
19

Either to always take the lower integer value
20

So whenever you face 1.63
21

You'll always charge 1
22

or
23

You have the option of charging the higher integer value
24

Or
25

You'll round it off
26

Using the rounding off function
27

All these three will give you three different results
28

So find out the total sales revenue if you charge the lower integer value
29

The total sales revenue if you charge the higher integer value and the total sales revenue if you are rounding off
30

With these two simple activities we will be sure that
31

You have learnt the mathematical functions taught in the previous section and you are ready to move on to the next section
