The newest calculator in the HP graphical stable. Programmed from scratch in native ARM code, and with a 127 x 256 pixels screen with gray levels, it is much faster than previous HP calculators and also than the competition. The solid feel makes it an ideal calculator for school, in particular for those countries that do not allow CAS devices in class.

Put HP's ultimate graphing calculator to use. Perfect for surveying, engineering, math and science professionals and students. Make use of a powerful SD card slot. Work how you like with RPN4, Textbook and algebraic entry-system logic. Enjoy lots of usable space on the largest, high-contrast screen. Utilize USB and serial connectivity3, HP Solve5, structured programming and Computer Algebra System (CAS).

The HP 50g is the latest calculator in the "49" series. The most apparent change is a revised color scheme, returning the unit to a more traditional HP calculator appearance. Using dark black plastic for the entire body, white, orange and yellow are used for function shift keys. The back shell is textured more deeply than the 49g+ to provide a more secure grip.

The form and size of the calculator shell is identical to the current 49g+ series, but four AAA batteries are used as opposed to three in previous models. In addition to all the features of the 49g+, the 50g also includes the full equation library found in the 48G series(also available for the 49g+ with ROM 2.06 and above), as well as the periodic table library originally available as a plug-in card for the 48S series, as of ROM 2.15, and has an asynchronous serial port in addition to IrDA and USB ports of the 49g+. Like the 49g+, the range of the infrared port has been limited to about 10 cm (4 inches).

The HP-28 was the first calculator capable of solving equations symbolically. They were replaced by the HP-48 series of calculators, which grew from the menu-driven RPL programming language interface first introduced in the HP-28 series.

The HP-28 calculators shared a flip-open (book style) case. On the left side of the flip, there is an alphabetic keyboard (in alphabetic order). On the right was a typical scientific keyboard layout. The display was a 137x32 LCD matrix, usually displaying four lines of information (3 stack/command lines, plus one softkey label line).

Your ideal classroom graphing tool uses a Computer Algebra System (CAS), familiar algebraic entry-system logic and displays answers in symbolic, numeric and graphing views. Create and store Aplets with 256KB RAM memory. Easily share data and connect to PC.
