This document provides instructions for a Christmas quiz with two riddles. Solving the first riddle of finding the square of the third prime number results in the number 9, which corresponds to the letter I. Solving the second riddle of evaluating the function f(x)=2^x-2^1 with x=2^2 results in the number 6, which corresponds to the letter F. Participants are asked to write the letters on paper and hold them to their webcams, with the intent that all letters combined from different countries will form a sentence.

1. Christma(th)s
A little quiz for the Christma(th)s
flashmeeting from the team of
Amsterdam.

2. The task
Solve the following two riddles/tasks on
the next two slides. Each solution has a
number as an outcome. This number
corresponds to a letter from the
alphabet (a=1, …, z=26).
Write each letter on a separate piece of
A4 paper. As big as possible. Then hold
it in front of the webcam. All letters
combined from all countries form a
sentence.

3. Letter 1
This is the square of the third prime
number

4. Letter 2
This is the outcome of f(x)= 2^x-2^1
when you fill in x=2^2
