Inhoud

Aktiwiteit: om te herken, te beskryf en te gebruik [lu 1.12.2]

1. Kyk weer goed na die eienskappe van vermenigvuldiging wat jy tot dusver bestudeer het. Voltooi dan die volgende:

17 x (15 x 13) = (_________________________x 15) x 13

(246 x 38) x 19 = 246 x (_____________x _____________)

_______________________ x (526 x 59) = (63 x 59) x 526

(349 x _______________________) x 68 = 72 x (349 x 68)

Nog iets om te weet!

Die DISTRIBUTIEWE EIENSKAP van vermenigvuldiging maak dit baie makliker om die produk te bereken.

Bereken die antwoord van die volgende:

(7 + 3) x 5 = _________________________________

(7 x 5) + (3 x 5) = _____________ + _____________ = _____________

Dus: (7 + 3) x 5 = (7 x 5) + (3 x 5)

2. Werk saam met ’n maat en vul die ontbrekende antwoorde in:

a) 68 x 27 = 68 x (_______________ + _________________)

b) 94 x 536 = 94 x (_______________ + _____________ + 6)

= (94 x _______________) + (94 x _______________) + (_______________x 6)

KOPKRAPPER!

4 Voltooi die volgende tabel deur net ’n regmerkie () of ’n kruisie () in te vul:

Eienskap geld vir vermenigvuldiging geld vir deling geld vir optelling geld vir aftrekking
Kommutatiewe ____________ _______ _______ _______
Assosiatiewe ____________ _______ _______ _______
Distributiewe ____________ _______ _______ _______

Tyd vir selfassessering!

Kom ons kyk hoe het jy tot dusver gevaar! Lees die kriteria goed deur en merk dan net die blokkie wat waar is vir jou.

Assessering

Leeruitkomste 1: Die leerder is in staat om getalle en die verwantskappe daarvan te herken, te beskryf en voor te stel, en om tydens probleemoplossing bevoeg en met selfvertroue te tel, te skat, te bereken en te kontroleer.

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

1.12.2: die kommutatiewe, assosiatiewe en distributiewe eienskappe van heelgetalle.

in what situation (s) would be the use of a scanning electron microscope be ideal and why?
Kenna Reply
A scanning electron microscope (SEM) is ideal for situations requiring high-resolution imaging of surfaces. It is commonly used in materials science, biology, and geology to examine the topography and composition of samples at a nanoscale level. SEM is particularly useful for studying fine details,
