I tend to agree with all of that @blockurator. I hadn't really paid a great deal of attention to the Maths side of things, but you're right. I teach Year 7 Maths, and we rarely allow the use of calculators, but by the time they get to Year 10, they are expected to have one of those graphics calculators. Pretty much does everything for them, so I guess we have to hope that they learned enough during the punitive years and are able to carry that for the rest of their lives.
