AM Calculator Pro

The AM Calculator Pro is the second, more expensive model in the AM Calculator line of scientific calculators. It is again manufactured by AM Studios, with a public release date of June 28, 2018.
Unlike the original AM Calculator model, which took heavily influence from basic calculators, the AM Calculator Pro is more comparable to a traditional scientific calculator in terms of keypad design and functionality. It is also fully redesigned for more practical use; this is in contrast to the original model, which included several elaborate hidden menus and minigames, a psychotherapy mode, and a haptic motor that was only used for a single moment. The original AM Calculator is theorized to have largely been a viral marketing campaign to build awareness around the brand and cement AM Studios as a major player in the calculator industry.
==Design==
The AM Calculator Pro has a black casing with a 512×384 black-and-white dot matrix screen, at a four-times-greater resolution than that of the original AM Calculator.
This model has a 35-button keypad including the arrow buttons, which is 11 more buttons than are present on the original model. There are now vertical arrow buttons that allow for scrolling through entry history and deleting individual entries, and through the new catalog menu.
The AM Calculator Pro also uses a completely new operating system that supports the increased screen size, the new standby mode, MATHPRINT-style formatting (notated using halfwidth rather than fullwidth characters), and other workflow adjustments.
==Functions==
The AM Calculator Pro supports a variety of functions, including algebraic operations, constants, trigonometric functions, combinatorics, and calculus.
This model also comes with a dedicated catalog, which includes several functions that otherwise cannot be inputted, such as hyperbolic trigonometric functions.
The keypad functions are documented as follows, from bottom to top, left to right, excluding the arrow buttons. The ⬚ symbol generally indicates a fillable field in a function that supports MATHPRINT-style formatting.

==Easter eggs==
As with the original model, several easter eggs are included within the software of the AM Calculator Pro, albeit in vastly lesser quantity.
Returning an error message causes the calculator to unlock a few games that become accessible exclusively through the catalog menu. These include Checkers, Pong, Snake, Tetris, and Tic-Tac-Toe.
