They were the successor models to the CFX-9970G, the first Casio calculator with computer algebra system, or CAS, a program for symbolic manipulation of mathematical expressions.

A more capable variant called Algebra FX 2.0 Plus was released in 2001 with additional functionalities for financial calculation, statistics, and differential equations.

The calculators were designed for usage in the classroom, where target markets were students and educators.

[1] They were aimed at helping students learn to solve algebra problems, where step-by-step solutions could be auto-generated.

[2][3] The Casio's CAS was mainly developed by its R&D team and Professor John Kenelly of Clemson University.

The Algebra FX 2.0 Plus was discontinued in 2003 and succeeded by the Casio ClassPad series, which has a stylus-based touch screen.

However, the Graph 100+ continued to be sold in France until 2015, until Casio removed the product from its website.

[3] The calculators consume power at the rate of 0.2 W. Based on the manufacturer's data sheet, zinc-carbon R03 AAA batteries and alkaline LR03 batteries can supply power for 140 hours and 230 hours for continuous display of main menu.

The Algebra FX 2.0 incorporates a black-and-white LCD Dot-Matrix display with a graphic resolution of 128 by 64 pixels.

The main menu consists of icons referring to different operating modes and applications.

Inside each mode, the bottom line is reserved for up to 6 function key menu shortcuts, which can be selected from buttons F1 to F6 on the calculator's keyboard.

The lower part of the keyboard consists of numeric and operational keys, where the EXE button is used to execute calculations and select commands.

The SHIFT and ALPHA keys are used to access functions and alphabets appearing on top of buttons.

In terms of keypads, there are two main differences between the Algebra FX 2.0 and its French version, the Graph 100+.

[7] The microprocessor is tuned at a clock frequency of 8 megahertz and supports the Intel 8088 instruction set.

[8] The Algebra FX series is capable of generating different types of two-dimensional plots.

The calculator can solve simultaneous linear equations up to 30 unknown variables and polynomials of degrees up to 30.

This was a huge improvement from its predecessor CFX-9970G, where only six variables are accepted for simultaneous linear equations and three is the maximum degree the polynomials can take.

Given an initial starting value and range, the module will calculate one nearby root and return to the users.

The PC programs that deal with the communication are the FA-123 and FA-124 (newer version) PC-Link, where transfers of data and screenshots are managed.

On the technical side, the SB-87 cable is based on a US patent 5504864, where the technology was previously used in the Casio's digital diary models.

The chip MAX232 or MAX233 by Maxim Integrated was a core component used to level-shift the voltages between the RS-232 and TTL standards.

[15] The same features are also seen in other calculator manufacturers such as the Texas Instrument's Calculator-Based Laboratory and the Hewlett Packard's StreamSmart.

[3] Different types of tests, including Z-test, T-test, χ2-test, and F-test, can be calculated based on inputted data, along with ANOVA analysis.

All additional functionalities appeared in the Algebra FX 2.0 Plus, except the tutorial mode, are carried to its successor line, the Casio Classpad series.

[3] Correspondingly, the calculators can store different types of data, including lists, tables, graphs, and matrices, in the main memories so that users can recall them later.

For instance, lines and circles can be drawn directly into the screen either by controlling each pixel individually or by calling readymade functions.

In the United States, the Algebra FX 2.0 and the Algebra FX 2.0 Plus are allowed by the College Board on the SAT, the SAT Subject Tests in Mathematics, and AP examinations in Biology, Calculus, Chemistry, Physics, and Statistics.

[19][20][21] However, the calculators are banned from the ACT examination due to their capability in the computer algebra system (CAS).
