Mmmm...Braaaiiinzz....
Today at Gin Gin SHS we have mathemetician, Dr Rob McDougall, in residence. How cool is that? Usually they are writers or artists. Today he introduced us to some Vedic maths. I am delighted now to have a method for mentally calculating 3 digit x 3 digit multiplications WITHOUT all the columns. WOO HOO!!!
