Thank you Mr J! I'm in 5th grade and I'm finding it hard to multiply decimals, and the way my teacher explains it is much more confusing, the way you removed the decimal helped me understand it better and I believe I can have a better chance at getting the questions correct because of you.

Thank you, very helpful video. I have a question about annotation of carrying. I was taught to put the number below the next space to the left in small writing (i.e. in below, in the product rows just underneath the place where the total will be that it is added to). I've noticed schools now teach for it to be above (as you have done), but this does lead to confusion - e.g. was it used and for what, and the needed to cross out so to not used again - as you've done. Another downside is that one can't go back to check the working out for errors. Is there a reason it's taught this way now? It seems less useful to me.
