3. Kom ons kyk nou wat gebeur wanneer ons enige getal deur 0 deel. Werk weer saam met ’n maat en doen die volgende met behulp van jou sakrekenaar:

3.1 6 ÷ 0 = ................................... 3.2 38 ÷ 0 = ..............................

3.3 438 ÷ 0 = ............................... 3.4 1 679 ÷ 0 = .........................

  • 63 827 ÷ 0 = .........................

4. Waarom gee die sakrekenaar hierdie antwoorde?

Onthou jy nog?

Deling deur 0 is nie toelaatbaar nie. Ons sê dit is ongedefinieer.

KOPKRAPPERS!

Ek dink aan ’n getal. As ek 3 aftrek en die getal deur 6 deel, is die kwosiënt 7.

Wat is die getal? ..................

Ek dink aan ’n getal. As ek dit halveer en dan deur 12 deel, is die kwosiënt 9.

Wat is die getal? ..................

Aktiwiteit 4:

Om verskillende maniere van skryf in verskillende kulture te beskryf en te illustreer [lu 1.2]

Het jy geweet?

Die Chinese skryf óf van bo na onder óf van links na regs. Van hulle syfers lyk so:

1.

2.

3.

4.

5.

6.

7.

8.

9.

10.

100.

1.1 Kan jy die volgende in Chinees neerskryf? Gee dan die antwoord in ons getallestelsel.

a) 10 ÷ 1 = .........................................................................................................
b) 100 ÷ 10 = ...........................................................................................................
c) 9 ÷ 3 = ..........................................................................................................
d) 100 ÷ 4 = ...........................................................................................................
e) 100 ÷ 5 = ...........................................................................................................
f) 100 ÷ 7 = ............................................................................................................

Deling deur 10, 100 en 1 000

Aktiwiteit 5:

Om waargenome patrone en reëls in eie woorde te beskryf [lu 2.2]

1. Sekere reëls in Wiskunde maak dit vir ons maklik om vinnig ‘n antwoord te bereken. Ons moet egter eers die reël kan “raaksien” of “aflei” voordat ons dit kan toepas. Werk saam met ’n maat en voltooi die volgende tabel:

Getal 20 50 90 120 360 1 470 2 560 14 380 26 520
÷ 10 ............ ............ ............ ............ ............ ............ ............ ............ ............

Wat merk julle op as julle na die antwoorde kyk?

2. Voltooi ook die volgende:

Getal 300 800 1 200 2 600 14 700 32 500
÷ 100 ................. ................. ................. ................. ................. .................

Kan julle ’n reël vir deel deur 100 neerskryf?

3. Kan julle ook die antwoorde van die volgende neerskryf?

Getal 5 000 7 000 13 000 45 000 126 000 382 000
÷ 1 000 .................. .................. .................. .................. .................. ..................

Wat gebeur wanneer ons deur 1 000 deel?

Deling deur veelvoude van 10 en 100:

Aktiwiteit 6:

Om te bereken deur geselekteerde bewerkings te gebruik ]lu 1.8.4]

1. Jy het nou reëls ontdek vir deling deur 10, 100 en 1 000. Kom ons kyk nou na deling deur veelvoude van 10 en 100. Werk saam met ’n maat deur die volgende berekenings:

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
