This compilation cassette contains five subprograms, all of which can be selected from a menu without the need to load any further files.

The programs however leave something to be desired. The first is Rectangles, where you have to estimate the area of one rectangle in terms of another. This is not an easy skill, and not as useful as a simpler area calculation program might be.

Monster Maths, the title program, is quite good, with you or your friends being eaten by the monster depending on your performance in answering three problems in a set time span.

Both the Times Tables and Arithmetic programs are simple drills of no particular note or merit.

The final, Mystery Numbers, program is very like a certain TV quiz show, where you are given a target number and have to form that number from the other numbers given by combining them in any mathematical sequence.

The difficulty is that in this program, even Level 1 can give problems like finding 468 from 21, 18 and 12. This may be fine for adults, but not for the target age group.
