I’ve been looking at Vedic maths for the past few weeks! It’s really interesting to try out different methods for multiplication! It’s quite amazing how quickly you can work out some challenging calculations from learning a few rules!

Not sure if it’s a method I will adopt but I am enjoying playing around with it !

Thanks for sharing
