ti 86

TI-85/TI-86. Ti-85 and TI-86 are the best calculators ever made. Of course without CAS. CAS is very nice feature but, as we can see, it leads to more complicated user interface. My preference is use PC/notebook insted them. TI-85 and 86 are powerfull calculators with genial user interface. It is pleasure to use them. apa itu ron 86
