Aktiwiteit: om die eienskappe van optelling te herken en te gebruik [lu 1.12.2]

1. Onthou jy nog dat ons in Graad 5 (Module 1) na die eienskappe van optelling gekyk het? Gebruik nou jou kennis!

Werk saam met ‘n maat en vind uit of die volgende waar of onwaar is. Jy mag jou sakrekenaar gebruik:

1.1 2 623 896 + 2 346 213 = 2 346 213 + 2 623 896


1.2 54 236 + (28 912 + 46 852) = (54 236 + 28 912) + 46 852


1.3 (128 435 + 239 416) + 1 379 538 = 128 435 + (239 416 + 1 379 538)


2. Voltooi die volgende sonder ’n sakrekenaar deur net die ontbrekende getalle in te vul:

2.1 456 213 + = 2 236 994 + 456 213

2.2 1 198 235 + (469 203 + 2 069 523) = (____________ + ____________)

+ 2 069 523

2.3 (264 059 + 3 016 438) + 1 269 055 = ____________ + (3 016 438 + ____________)


Leeruitkomste 1: Die leerder is in staat om getalle en hul verwantskappe te herken, te beskryf en voor te stel. Hulle kan ook met bekwaamheid en vertroue tel, skat, bereken en kontroleer tydens die oplos van probleme.

Assesseringstandaard 1.12: Dit is duidelik wanneer die leerder herken, beskryf en gebruik:

1.12.2: die kommutatiewe, assosiatiewe en distributiewe eienskappe van heelgetalle (leerders behoort in staat te wees om die eienskappe te gebruik sonder om noodwendig die name te ken).

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
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.
what is the actual application of fullerenes nowadays?
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.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
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.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
What is lattice structure?
s. Reply
of graphene you mean?
