This project contains copies of questions created for Newcastle University's courses, mainly the Mathematics and Statistics degree.

## Project activity

#### Christian Lawson-Perfect on Truth tables 4 (v2) 4 days, 17 hours ago

Saved a checkpoint:

Replaced javascript in part b with a custom marking algorithm.

#### Christian Lawson-Perfect on Simplex method - 4 or 5 random inequalities 4 days, 17 hours ago

Saved a checkpoint:

Replaced javascript in part a with a custom marking algorithm

#### Christian Lawson-Perfect on Finding bases for the null space and row space of a matrix 4 days, 19 hours ago

Gave some feedback: Doesn't work

#### Christian Lawson-Perfect on Find n such that $\sigma(n)$ is the given number 4 days, 19 hours 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 4 days, 19 hours ago

Gave some feedback: Needs to be tested

#### Numbas Admin on Find n such that $\sigma(n)$ is the given number 4 days, 19 hours ago

Automatic testing has identified a problem with this question:

Part b got 0 credit

#### Numbas Admin on Find n such that $\sigma(n)$ is the given number 4 days, 19 hours ago

Gave some feedback: Doesn't work

Saved a checkpoint:

Replaced javascript with custom marking algorithms.

Saved a checkpoint:

Fixed the pattern-matching code for Numbas v4. Could all do with being a custom marking algorithm, though.
