This retro gaming controller calculator is one way to make sums a whole lot more fun. Available from Urban Outfitters, it has applied the functions of a calculator to the looks and shapes of a classic gaming handset.
There are a lot more keys than on your average controller: your addition, subtraction, multiplication and division keys are found where you would normally find the directions, while instead of the usual jump and attack keys you've got such delights as the square root and percentage functions.
Designed to help you master problems even more challenging than the average game, the calculator costs £12.
