Singapore definitely copied Russia. Lee Kuan Yew, the architect of modern Singapore, was extremely open about his plan to copy the best examples of everything from all over the world, and Singapore did an astoundingly good job of it.

Thank you, but would definitely need an English version.

Hi, I've heard fantastic things about "Mathematics 6" by Nurk and Telgmaa, but Perpendicular Press seems to have disappeared and I can't find this anywhere. Does anyone know where a PDF copy might be available? Happy to pay, can't find a print or digital copy to buy anywhere.
