• When you did an easy problem like 0.3-0.2 all I did was subtract 3-2=1 and added the 0 first the the decimal and lastly the number 1 getting this decimal 0.1. Anyway besides this easy problem why didn't you do it like this for an easy problem?
• Mr. Sal uses a strategy to that shows you an easier problem first, so when you get to more difficult ones you are not overwhelmed. (he will go to more difficult ones later on)
• At in the video, I don't get what he is trying to say?
• When subtracting 1.5-.7, you can break it down in many ways. At this time stamp, Sal is breaking it down to 1.5 - .5 - .2 because 1.5-.5 is easy to do and then 1-.2 is easy. That way it may be easier to do in your head.
• I'm literally dying
• subtracting with decimals
• At :39 he talks like it is 1st grade math.
