Unfortunately, this Quiz will not be able to receive a prize:
Missing explanations. Explanations repeat the same text "Klammern zuerst rechnen" in #q4 - #q15.
1. The first half of the questions all have the same explanation, "Klammern zuerst" (parentheses first). It would have been better to provide a derivation of how the answer has been arrived at.
2. In the section about famous mathematicians, the explanation is always "X was a famous mathematician". Here, it would have been better to actually provide context on who these people were.
3. Questions 16 and 19 are incorrect: a² + b² is not always c². Example: a = 1; b = 2; c = 4: a² + b² = 1² + 2² = 5 ≠ c². It is necessary to specify here that we are talking about the sides of triangles.
4. Some answers (e.g. 3 and 5) are confusingly written: A squared number is not shown like "b²" or "b^2" but rather "b2", which can easily cause problems like in question 5, where the answer is " 70a2b – 42ab". It is unclear whether the first term refers to "70a²b" or "70a 2b".
5. Question 17 refers to "Zeh" (translated "toe"), I can only assume this is a misspelling of the letter "C".
6. Question 29: Math is actually not really a "Naturwissenschaft", although school systems often group it as such. It is more accurate to describe it as a "Strukturwissenschaft" or "Geisteswissenschaft"[1].
