i hope this helps!! btw rmb to post the qns too, i saw that the qns was on the other side of the page, maybe you can write the qns in the same place as the qns so it is more convenient for everyone who is willing to help :> if there's anyone seeing this, can u pls comment if the concepts and everything are correct because im also a sec 3 student who js finished this chpt and wanted to help out :) i appreciate any comments for improvement and etc.
