Questions testing understanding of the precedence of operators using BIDMAS, applied to integers. These questions only test DMAS. That is, only Division/Multiplcation and Addition/Subtraction.

determine the least residue mod n of a given number.

Round random numbers to the closest whole number, 1 to 3 decimals places. Also rounding that could show common misunderstandings.

Useful for a review of the base 10 number system before introducing different bases and also just ensuring students understand how the base 10 system works.

A sneak peek at a really clever integration of GeoGebra with Numbas.

6 questions which introduce the user to the Numbas system.

This activity has a variety of percentage questions all designed to be done without a calculator.

Q1 is useful for MfB

Q2 is useful for MfB - wording to look at?

Q3 I don't understand this Q, should be removed or re-worded

Q4 good questions but too many, make them more business like

Find a regression equation.

Now includes a graph of the regression line and another interactive graph gives users the opportunity to move the regression line around. Could be used for allowing users to experiment with what they think the line should be and see how this compares with the calculated line.

Statements about the different kinds of averages where you have to select "always", "sometimes", or "never".

Simple Question to find the mean of five numbers

This quiz poses questions on basic probability and statistics.

Testing factorisation of quadratics.

Several quadratics are given and students are asked to complete the square.

Some impossible-looking questions about quadratic equations which can be solved with a bit of thinking.

Lay out gapfills so the student has to enter either the numerator or denominator of a fraction.

Questions to test if the student knows the inverse of fractional power or root (and how to solve equations that contain them). 

Two ordered data sets, each with 10 numbers. Find the sample standard deviation for each and for their sum.

The student is asked to factorise a quadratic $x^2 + ax + b$. A custom marking script uses pattern matching to ensure that the student's answer is of the form $(x+a)(x+b)$, $(x+a)^2$, or $x(x+a)$.

To find the script, look in the Scripts tab of part a.

A student selects a card from a deck of 52 and rolls a dice once.
