Question in Programming extension
This question shows how to use the programming extension's run_code function to run some Python code and use its result in the marking of a non-code part type.
Python is used to calculate the correct answer for a number entry part type. This could be done

Question in Programming extension
The student must write code to compute the standard deviation of an unknown list of measurements.
The suggested answer uses numpy.std.

Question in Programming extension
This is the simplest demonstration of the "code" part type I could think of: assign
x = 1
.An alternative answer gives a hint if the studen'ts code doesn't define x at all.

Exam (6 questions) in Getting Started
A collection of information and activities to introduce students to Numbas. There is some information on how Numbas works, information on how to write answers to mathematical expression and number entry parts, and a "test yourself" explore mode activity.
Note: This exam was written for students accessing Numbas exams through the Numbas LTI tool. Some of the information does not apply to exams accessed standalone or through a generic SCORM player.

Exam (12 questions) in Demos
A demo of the main new features in Numbas v5: explore mode, alternative answers and "Choose from a menu" question navigation.
-
Question in Demos
All the answers in this question are equations. In order to mark each equation, Numbas needs to pick some values that satisfy the equation and some that don't, and check that the student's answer agrees with the expected answer.
Any equation with the same solution set as the expected answer will be marked correct.
-
Question in How-tos
The answer to this question is a differential equation involving $y''$, $y'$ and $y$.
A variable value generator for $y$ ensures that the right values are tested to check that the student's answer is equivalent to the expected equation.

Question in pre-algebra Numeracy and Arithmetic
Fractions already have a common denominator. Addition and subtraction 50:50 split, when subtracting, the answer is negative half the time. Students shouldn't have to worry about reducing fractions by design.

Question in Ida's workspace
Use two points on a line graph to calculate the gradient and $y$-intercept and hence the equation of the straight line running through both points.
The answer box for the third part plots the function which allows the student to check their answer against the graph before submitting.
This particular example has a positive gradient.

Question in Standard Maths
Students are shown one of 5 different radial surveys and asked to answer one of 8 questions about it.
2 questions ask for the length of a side.
2 questions ask for the value of an angle.
2 questions ask for the area of a triangle.
1 question asks for the land area, and 1 question asks for the land perimeter.
The values are hard coded. In cases where your choice of precision affects your answer, a range of answers is accepted, and a comment is made in the advice to that effect.
-
Question in Standard Maths
Students are given the equations of two lines in the form y=mx+b and asked if they are parallel.
The line equations are randomised.
The answer is yes or no. There is a 1 in 6 chance of the lines being parallel.

Question in Ed questions to share
Used for LANTITE preparation (Australia). NA = Number & Algebra strand. Students must do a simple interest calculation (geven principal, rate and months, all of which are randomly generated) then subtract their answer from the supplied compound interest amount to find the difference.
