Part A seem to be bugged in some cases:

for 4i*(-7+7i) revealed answer is -28 - - 28i, and the correct answer is not accepted.

#### Christian Lawson-Perfect on Truth tables 4 (v2)8 months, 1 week ago

Saved a checkpoint:

Can't convert grids of booleans to matrices automatically any more, so I've added a function 'bool_matrix' to do that.

Saved a checkpoint:

Replaced javascript in part b with a custom marking algorithm.

#### Christian Lawson-Perfect on Simplex method - 4 or 5 random inequalities8 months, 1 week ago

Saved a checkpoint:

Replaced javascript in part a with a custom marking algorithm
