They use calculators for everything.
Try asking them to do some simple mental arithmetic.
IMO it's the basics that aren't taught in the right way these days (X tables by rote for instance) at infant school level.
These are the skills upon which everything else is based, and which are absorbed so well at that young age.
In the Philippines they still use that method, and I believe my children were put at an advantage because of that, when later entering the British system.![]()
