@acelaces: Thanks for the comment and you make a good point about the reasoning behind the borrowing. It also seems like you have a better understanding than you give yourself credit for, because as you state
"'we borrow 1 from the 10s column so we are borrowing 10 really".
and in this case we should take '1' and '10' to be base 2 numbers (equal to '1' and '2' in base 10).
this was very good, the practice is clear but i am still left a bit unclear about WHY 10-1=1 even though i can understand it by converting it to 2-1=1. I wish you would point out the similarities between the reasoning with decimal subtraction and with binary subtraction so i can get the understanding. like 'we borrow 1 from the 10s column so we are borrowing 10 really'

Sorry for the audio fading in and out. I don't think I had the external microphone hooked up.
