1 1 1 Get ting Star ted The HP Pr ime Gra phing Calculator is an eas y -to -us e yet po we rful graphing calc ulator designed for secondary mathematics educati on and be y ond. It offer s hundr eds of functi ons, and incl udes a comp uter algebr a sy stem (CAS) f or s ymb olic calc ulati ons.
2 2 • Bread-c rumb notation is used to r epre sent a selecti on fr om sub-menus or sub-sub-menus . For e xample , “Select Polynomial > Algebra > Quotient ” means f irst selec t Polynomial , then select Algebra , and finall y selec t Quotient .
3 3 Adap ter W arnin g • T o r educe the risk of electr ic shoc k or damage to equipment , only plug the wall ad apter int o an A C outlet that is easil y accessible at all times .
4 4 Na vigat ion The HP Pr ime off ers two modes of na vigati on: b y touch and by k ey p r ess. In man y case s, y ou can tap on an i con, f ield , menu , or objec t to select (or des elect) it . F or ex ample , you can open the Functi on app by ta pping once on its icon in the Appli cation L ibrary .
5 5 Alternati ve ly , yo u can just ta p the field or f ield label , and: • if the fie ld allow s you t o enter data o f yo ur choi ce, ta p it, e nter y our data, and ta p . • if the field allo ws y ou to c hoose an item fr om a menu , tap on it t w ice and se lect the item yo u want .
