Observation

Today I learned that they do math with slightly different conventions in India than we do in the US. I would have assumed (though I had not actually thought about it before), that they would use the same conventions we do because we were both British colonies at some point in time. But nope. Maybe the slight variations date from the great Indian mathematicians of old, like how we've inherited some conventions from Newton. In any case, it's pretty cool because learning things in a different way means there is more possibility for intellectual diversity.

Cool.
