    \textbf{{Ancient Egytian Calculations}}\\<ol type=a><li>
    Use the following example to explain how the ancient Egyptian method of multiplying two numbers (in this case: ${y[1]}\cdot{y[0]}$) works. 
    {egyptian(y[1],y[0])}
    </li>\\
    <li>    
    Using the ancient Egyptian method, solve the division task ${x[0]}:{x[1]}$.
    The first and last line of the solution is already given below.
    </li>\\
    <li>
    Using $180:27$ as an example, explain why not all division tasks can be solved in this way, even if you allow unit fractions in the form $\frac{{1}}{{2^n}}$.
    </li></ol>\\ 
    \item This task has to be corrected manually, sorry!
