Maths task

Task description:

For this task description was a bit hard because I was stuck on 2 questions.  Question 3 and 10. (I hardly think of that...)  But anyways, It was fun to do, it took me 6/7 minutes. Because question 3 and 10 were hard to figure out.  But I solved it by myself. But I would say some of the questions were easy. Like not all of them.  just only 2 were hard.  so bye now...
