Multiplication means … Part 2

April 4, 2014

Well, after load of comments about whether 6×4 is four groups of six or six groups of four and Colin Beveridge disagreeing with me (and being rude about to boot) I’m pleased to say…

James Grime and Numberphile are on my side! James says “multiplication is just glorified addition. If you want to do 5×10, you just do five plus five plus five and so on ten times.”
This is clearly ten lots of five, not the other way round.
