My 6th grader could (and did) solve all of these except for the trig and integration. The puzzle was fun but not all that challenging. It might look hard at first, but the problems are really quite simple. 14 x 14 x 14/14 x 14 is clearly 14 not infinfity or zero or any such nonsense.
To Furienna: No offense, but I thought European schools were supposed to be far superior to American schools, especially in math and science education. I’ll be a bit more skeptical from now on whenever ads tout “European engineering” to entice me to buy an expensive car or gadget.
