    Am I the only one that got so excited when I saw his calculator? I've never seen a pink colored one. Kinda weird for me but I want it. This video was useful to me, covered the chapter beautifully 💕

    If I may be so bold, I think precision = the number of decimal places your data is measured in rather than the consistency across a data set. Consistency across a data set is called 'reliability' I think

    Hi there, I find your videos well explained and very informative. Is there a possibility that you could make it possible so that I may be able to download your mind maps for each of your videos? For example, when making a video, you would take a picture of the mind-map and put it on your website so that we can download it. That is if you have any time. Thank you, Sir!

    Answer this question for me, please, is a head scratcher:
    1.0 cubic centimetre (cm^3) of a solution contains 0.010g of salt. What is the mass of salt contained in 1 cubic decimetre (dm^3) of the same solution?
    Textbook says 10g but I disagree, my answer is 0.1g
    Which answer is correct and Why???

    • @lilgooseboi7354
