Bernd and Marias grandpa was visiting them. He brought a book with a secret code..

“This is a secret free mason alphabet. The secret code for “Maria“ looks like this.“, said grandpa.

How does the secret code for “Mike“ and “Lisa“ look like. - 1 blue point for each of them.
Bernd watched a movie and had seen a secret message from a chemist. When he used the code methode for his name ist was 56860. Which number is W O C H E N A U F G A B E – 4 red points. (If there is more then one solution, just write down one of them.)
Solving the picture-puzzle will get you two extra blue points, provided you also got points doing the regular maths problem. The rule for each picture puzzle is: Each icon represents one digit, same icons, same digits, different icons, different digits. ©HRGauern[at]@t-online.de
