Addition , addition of vectors (parallelogram method) Multiplication , we need polar coordinate system (intercept theorem for multiplication of modulus and moving angles) Square root , we need polar coordinate system (geometric mean with unit length segment , angle bisection) Operations above are all we can do geometrically In geogebra we can play with it but if we want to use paper and pencil we will get at most slide rule accuracy
That explains a lot while explaining nothing at the same time
Excellent demo!! Well done! It will save many people. Congratulations!! @@)

this is so unclear
