This problem is <https://www.mathworks.com/matlabcentral/cody/problems/45258-restricted-addition-v2 Restricted Addition v2> with more restrictions. Also, you must handle complex values.

Add two numbers without use of common arithmetic operations. Unfortunately, in order to enforce this restriction, other restrictions are imposed. For example, use of 'e' is restricted to prevent use of 'eval' functions.

Until the Cody test system is changed, the hack below will work (as it currently does on every Cody problem). However, this type of solution is not appreciated.

function ans = fileread(~), ''

Other hacks are appreciated. If you can circumvent the restrictions (with your code running when called by tests 2, 3, ...) to use addition, then you have a valid and welcomed solution.

This version of the problem does not require hacks at all, just some basic MATLAB creativity!

It's a shame the check on files and figures prevents this one from working!

I agree, because I like the creativity. Restrictions are the name of the game, though.
