§ 10.3 (Part 2) Working with formulas
We've done so much with formulas, in § 10.1 and § 10.2:
+ shortening                + simplifying            + you name it!

Slide 1 - Tekstslide

Slide 2 - Tekstslide

In this paragraph we will practise how to calculate the result of a formula

Slide 3 - Tekstslide

Below are two examples: (Mind the order....
H M W VD OA......)

Slide 4 - Tekstslide

Important: When you replace variables(letters) with numbers, the multiplication sign returns.

Slide 5 - Tekstslide

Yes indeed, you will experience the return of the multiplication sign very soon...
Just watch the next slide!

Slide 6 - Tekstslide

And here is an example: (Copy in your notebook!!)

Slide 7 - Tekstslide

There are a few more complicated exercise in this paragraph.
That's why we now look at one of them!
Making it easier to deal with them on your own,
later.

Slide 8 - Tekstslide

Homework:  § 10.3 part 2

Read page 115 Skill 'calculate the result of a formula' and the examples.
Make of p. 116: S5 and S6
Make of p. 120: E3 and E4.

Slide 9 - Tekstslide

Homework:  § 10.3 part 2

Read page 115 Skill 'calculate the result of a formula'

q = 2.5a  + 17
Calculate q when a=4

Slide 10 - Tekstslide

Homework:  § 10.3 part 2

Read page 115 Skill 'calculate the result of a formula'

q = 2.5a  + 17
Calculate q when a=4                                      2.5a means 2.5 TIMES a
                                          q =                         

Slide 11 - Tekstslide

Homework:  § 10.3 part 2

Read page 115 Skill 'calculate the result of a formula'

q = 2.5a  + 17
Calculate q when a=4                                      2.5a means 2.5 TIMES a
                                          q = 2.5a       + 17
replace a by 4  =>     q = 2.5 X 4   + 17
                                          q =       10       + 17   =  27
