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.

#### Dirk Janssens on Arithmetics of complex numbers III 3 months, 3 weeks ago

Gave some feedback: Ready to use

#### 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 inequalities 8 months, 1 week ago

Saved a checkpoint:

Replaced javascript in part a with a custom marking algorithm

#### Christian Lawson-Perfect on Simplex algorithm - bus company 8 months, 1 week ago

Saved a checkpoint:

Replaced javascript for part h with a custom marking algorithm

Gave some feedback: Doesn't work

#### Christian Lawson-Perfect on Find n such that $\sigma(n)$ is the given number 8 months, 1 week ago

Saved a checkpoint:

Part b seemed to be just some debugging info, so I've removed it

#### Christian Lawson-Perfect on Find n such that $\sigma(n)$ is the given number 8 months, 1 week ago

Gave some feedback: Needs to be tested

#### Numbas Admin on Find n such that $\sigma(n)$ is the given number 8 months, 1 week ago
