In the magazine <<Australian PC World>>, June 1992, page 119, Mr.
Geoff Long reviewed, "SymbMath 1.4 belongs in a more esoteric field, that
of symbolic mathematics. If you've ever had need for programs such as
Maple or Mathematica, you'll know about symbolic mathematics, also called
algebraic computation or symbolic manipulation. SymbMath is a symbolic
calculator that can manipulate complicated formulas and return answers
in terms of symbols. It solves the same sort of problems as programs like
Mathematica, but still runs in 640 K of RAM as opposed to Mathematica's
4 Mb plus. Although SymbMath is still being added to, it has generated
interest in the scientific sections of some overseas electronic bulletin
boards, being one of the most frequently downloaded programs at some
monitored sites".
--------------------------------------------------------------------------
The <<IEEE Micro>> journal on February 1992, page 76, reviewed
"SymbMath, an expert system that solves mathematic problems in symbolic
formula or through numeric computation ... requires significantly less
RAM than most comparable software - 640 Kbytes, as opposed to as much as
4 Mbytes".

Editor G. Long of the <<Australian PC World>> magazine on 1993
July, page 147, reviewed "SymbMath 2.0 is a symbolic calculator that can
manipulate complicated formulas and return answers in term of symbols. It
solves the same sort of problems as programs such as Mathematica and Maple
(and some that they can't), yet runs within 640K of RAM."

--------------------------------------------------------
* Mathematics whizzes should find <SymbMath> a capable facility for
handling complex problems.
<Symbmath>, short for Symbolic Mathematics, is both an advanced
mathematical calculator and an expert system. Designed by Australian
Weiguang Huang for solving university and professional level symbolical
maths problems. <Symbmath> will also perform exact numerical
computation. It's able to manipulate extremely complicated formulae,
returning answers in terms of symbols, formulae, or exact numbers as
required. The program can learn from your calculations, automatically
adding your problem-solving techniques to its repertoire: making it of
interest to artificial intelligence researchers as well as mathematicians,
particularly as you don't have to write any code.
Its capabilities are impressive, going well beyond the facilities
offered by rival programs. It's very fast and includes wide-ranging
and sophisticated routines for differentiation, integration, equation
solving, algebraic calculations, exact and floating point numerical
computation of numbers ranging from plus to minus infinity, and an ex-
tensive array of other advanced facilities that will be more than enough to
handle academic or practical mathematical problems of even extreme com-
plexity.
Despite this extensive computing power, <Symbmath> will nevertheless
run on very basic hardware: you need at least 640 Kb of RAM and a hard disk,
but an 8088-based PC with a monochrome monitor is ample for even very
convoluted calculations. You'll need to be well-schooled in advanced maths
but, if you are, you'll will find <SymbMath>, well worth investigating.

Stephen Arnold on <<Refections>>, Vol. 18, No. 2, May 1993, page
58, reviewed SymbMath: "An alternative for MS-DOS users which has the
unique advantage of being `home grown', SymbMath is the only Australian-
made computer algebra system of which I am aware. SymbMath comes in three
versions (shareware, student and advanced), with corresponding increases
in price and in capabilities. The student version is reviewed here, and
was found to be a versatile and useful mathematical tool.
Like Maple on Macintosh, mathematical input must be entered in `computer
syntax', but SymbMath (like Maple V and Derive) has the option of two-
dimensional output, which provides a reasonable approximation of math-
ematical notation. Its capabilities are impressive, including a `chemistry'
option, in which it performs chemical calculations and operates on
chemical equations, and a unique ability to `learn' from the user.
Entering a rule for differentiation, for example, automatically `teaches'
the program how to integrate using that rule; trigonometric identities
and algebraic formulas can likewise be used as the basis for inference.
For all its algebraic capabilities, the program has no inbuilt graphics
component. Instead, it may be interfaced with another program, called
PlotData, from the same author (This also comes in three versions). I
found it a little slow in running, since it constantly accesses the disk,
and the user must change from Edit mode to Run mode each time a seres of
instructions is to be carried out. At the same time, the paired programs
provide more than adequate computer algebra capabilities, and represent
excellent value for money.
