Maths books upset more than 98% of the world. We have to be thankful that maths books are not (usually) banned.

This is why I took the precaution putting "usually" in parentheses.
At the beginning of 1970's there was still some positive echos of the new math movement in Japan. As a high-school student I read a Japanese translation of textbooks written by a group of authors in the USA closely connected to the new math movement. These textbooks left a deep impact on me.
I think the main problem with the new math. was that the average high-school teachers in most of the countries are not at all good enough to teach such stuff.
