Also for those interested in learning more about how education takes place in Denmark you'll see a lot of crap about "the pedagogy of education" and a bunch of teachers espousing their personal philosophy of learning. Ignore them. Look at what the students actually do, look at what the parents complain about, and look at the passing grades (30% on a MC questionnaire).
From about age 11 they are introduced to GeoGebra, Maple, etc. and the remainder of their education focusses on translating problems from paper into the computer and hitting solve - the result is unsurprisingly a bunch of students who "are great at mathematics" but don't even understand what a %age is (I took to helping my uni classmates who were struggling and I blew a guys mind when I explained %ages are just fractions, take the number and divide it by 100).
