Calculate trace of a matrix. Fixed matrices as the same as in our workbook.

Decide if matrix sizes match so they can be added.

Matrix addition, with the added test of whether they understand that only matrices of the same size can be added.

Students are shown a right angled triangle and asked to compute a side length using a trig identity.

The triangle is a fixed image, but the angles and side lengths are randomly selected.

The angle is given in degrees and minutes, and students are asked for the side length correct to 1 decimal place.

There are 4 different triangle orientations that can display.

Easy true/false questions to check if the meaning of a size of a matrix is understood, in terms of numbers of rows and columns.

Find the size of a matrix.

Checking whether a given set is a plane or not. Depends on whether two vectors are parallel or not. Then checking whether the plane goes through the origin. This is not always obvious from the presentation.

Not randomised because it's the same as in our workbook.

Simple scalar multiplication of a general vector with the important scalars 0, 1, -1. Just the variable name is randomised.

give the negative of each of two vectors. One always has 5 entries, the other has a random number of entries.

Identify the prime number
