Simple Interest (read only till simple interest: do not read compound interest and investment) – the formula used here is I = PRT instead of I = PRT/100 since they are changing R into a decimal first. Therefore, 100 is not needed any more...you can work this way in your exam as well.

I created this blog not just for all those of you who are still finding certain topics difficult to understand, but also to serve as a revision of what we did in class. I am attaching notes and videos to help you to understand more the topics we already did. Moreover, I am also attaching worksheets (answers included) which you can work out as extra work.
