Compare this machine to a calculator, it's like comparing a cruise ship in a fishing boat. It is really a tone above. This machine is packed with mathematical functions not common on calculators. This is going beyond the factorial and trigonometry. It can display the domain of a function, solve any equation a system generate lists and matrices according to a rule, develop, factoring, calculate the GCD, LCM, know the max or min of function etc ... In all, with about 300 functions! This machine is very competent in algebra, analysis, probability, statistics and financial calculation, complex numbers and trigonometry. It can function grapher, generate tables, all quite easily. There is even a spreadsheet! Variables created in a module can be retrieved in another. A fascinating machine that the user put a little time to master it thoroughly, but it's worth it!
