21:18 scaling down each mark BY 40% should mean that the number is multiplied by 0.6 and not 0.4 isn't it? if it was scaling down TO 40% then it should have been multiplied by 0.4 am i correct?
scaling down by 40% means multiply the number by 0.4 then subtract the result from the number ,scaling down to 40% means just multiply the number by 0.4 , that's a simple mistake in the video.

thanks man..

Yes obviously
scaling down by 40% means multiply the number by 0.4 then subtract the result from the number ,scaling down to 40% means just multiply the number by 0.4 , that's a simple mistake in the video.
It should be scaled down to 40%.
true it should be scaling down "to 40%"
15:49 Need this benevolence from every exam assessor
5×1 is 5 ...
no way
bro that's verbo (Textual mistake = Typo) so verbal mistake is verbo lol
