yakko: 7 times 3 is 21 wich as you know is just two 10's plus 1 and so we put the one right here and we carry the 2 one left to the top of the tenths place right next door, and we put it on top of the number 4, wich is really four tenths that we multiply times 3 in the ones place and that's why, we now have 12 wich we add to the 2 that we carry to get 14.
see how easy that was, Ho ho it's multiplication, yes math education, hey Albert Einstein said that it's so easy to do, it's simple it's breezy, it's fun and it's easy, so buy a calculator, you can multpily too.
and now the second digit! 7 times 8 is 56 wich as you know is just 5 tens plus 6 and so we put the 6 in the tenths place, left of the one, carry the 5 like we did before, to the top of the tenths place next to the 4 then multiply that 4 times 8 to get 32 see isn't this great, then we add the 5 that we carried before to get 37, then add once more, straight down to get 3901.
isn't this swell, oh lets give multiplication a standing novation, Issac Newton multiplied a couple times two, times, two, times two, it's simple it's breezy, it's fun and it's easy, just buy a calculator, and study this stuff later, maybe someday you can multiply numbers, 2..3..4..5..RECESS.
