Slide 1 - Tekstslide
The same 'order of operations' as you learnt applies now!
And you can take the
+ sum
+ difference
+ product and
+ quotient again!
+ above all the brackets 'rule' again, having top priority!

Slide 5 - Quizvraag
explanation:
First comes X and only then we do -, so:
6.6 - 4 x 1.5 =
6.6 - 6 = 0.6
Slide 6 - Tekstslide
Slide 7 - Tekstslide
Slide 8 - Tekstslide
5.6 x 0.01 = ....
A
5600
B
0.56
C
0.056
D
560
Slide 9 - Quizvraag
explanation:
multiplying by 0.01 is the same as taking
of that number, or placing the decimal point 2 places to the left, so:
5.6 x 0.01 = 0.056

Slide 10 - Tekstslide
Finally a remark about exercise 25:
In 25 the calculations have become that complicated, that it is important to work them out in a few steps!
Look at the following example.
Slide 11 - Tekstslide
This becomes pretty tricky, reason for us to work it out on paper like this:
0.1 x 14 x 100 = 1.4 x 100 = 140
So first the brackets, then the square and finally the 2 multiplications!
Slide 12 - Tekstslide
One more TASK:
4.2 + ( - 28) =
+ Copy this task in your Notebook
+ write down the CALCULATION and only then the ANSWER
+ take a picture and
+ send it in in the FOTOVRAAG!
