Question in HELM books
Students are given three expanded products and asked to write them in index notation. Part of HELM Book 1.2
-
Question in HELM books
Expand (x+a)(x+b)(x+c), where x is a randomised variable, and a,b,c are randomised integers.
Note that the pattern restriction in the marking checks that there are no brackets and that the expression is simplified to at most a single x^3, x^2, x and constant term; but it will let you get away with an additional -x^2 and/or -x term. (e.g., you could write 3x as 4x -x and the marking would accept this. This was to stop the pattern matching getting too complicated.

Question in Programming extension
In four parts, the student builds up the definition of a class representing a rectangle. First they write the constructor, then add methods to compute area and perimeter.
In the final part, they must use the methods to write a function which determines if a rectangle's area is larger than its perimeter.
-
Question in Programming extension
In the first part, the student must write an R function to compute the first $n$ terms of the series $\frac{1}{k!}$.
In the second part, they must use that function to calculate an approximation to $e$ using a given number of terms of the series.

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.
