A handful of programs to make the number-crunching game run a little smoother. The matrix program cleverly called Matricks handles all the common matrix functions on one of the little fellas - the matrices, that is - up to 37 squares wide and deep.

Plot is another imaginatively-named program that plots functions and uses GDOS to give good hardcopy. It can handle all the usual sine and cosine business as well as things called Bessal functions and integration. The Turing Machine Simulation is an - er, you guessed it, a theoretical type of computer developed to investigate and predicate calculus. There are also two calculators with a zillion functions each. Sub Cal takes readable expressions and the Take Note Printing Programmers' calculator can store operations and do all sorts of fancy operations on binary numbers.

These programs aren't really for the novice and, unless you're involved in actually doing your maths homework or maths is a serious hobby, this disk is unlikely to be much use to you - but if you're in the know it's the biz.
