Create a file solution.py in which you evaluate the following mathematical expressions and assign them to variables a, b, ...
(To view the mathematics nicely typeset, view the notebook README.ipynb or as a PDF README.pdf.)
\begin{align} a &= -1 + 2 \ b &= 102 - 201 \ c &= 12345678987654321 \times 9876543210123456789 \ d &= 3/2\ e &= \frac{1}{1 - 0.9^2}\ f &= 1 + \frac{2}{1} + \frac{2^2}{1\cdot2} + \frac{2^3}{1\cdot2\cdot3} + \frac{2^4}{1 \cdot 2\cdot3\cdot4}\ g &= -3^4\ h &= 2 - 5.5\times 10^{-7}\ i &= 1.672621898\times 10^{-27} \times (3\times10^8)^2\ j &= \sqrt{2}\ k &= \sqrt{-1}\ l &= (1 + 2i) + (-2 + i)\ m &= \frac{1 + 2i}{2 - i}\ \end{align}
Run the tests locally with
pytest
In order to perform autograding, git push your changes.
The first line in solution.py should be
a = -1 + 2
