The language of Mathix and Math-x 

Bhaskara is the computer algebra language for the systems Mathix and Math-x
Design There is a distinction between a full computer system (Mathix and Math-x) and the computer algebra language. This language will be called Bhaskara, after the inventor of the zero and positional system for numbers. Principles can be taken from Niklaus Wirth. See the formats to choose from: Rosetta. See this discussion of Fateman's 1992 Review of Mathematica. Currently, this page only gives basic ideas
Mathix allows dialects so that USE LANGUAGE starts the input in the syntax of that language. The default language is OBERON (a programming language rather than a computer algebra language). This page describes the syntax for USE BHASKARA. Bhaskara stays close to ASCII input (case sensitive, Latin and Greek) without the perplexities of MathML, but there will be a translator and editor for TeXmacs
Basic (* ... *) are comments
; is the delimiter
:= is assigment and =: is delayed assignment (lazy)
= is equality / identity and == is formal identity
expression brackets are [expr] = (expr) = expr (except when expr contains a comma) with freedom for readability
{a, ..., b} is an unordered list (a set), with a possible delimiter Given to allow for conditionality
(a, ..., b) = [a, ..., b] is an ordered list, with a possible delimiter Given to allow for conditionality
f(x) or f[x] are "labelled brackets" or a call of function f with variable or value x (again freedom for readability)
<a, b> is an open interval and =< a, b >= or &le; a, b &ge; the closed interval (with the permuations of brackets)
Sin and Cos are functions, with names like John and Mary
StandardFunction is the format for naming (and not STANDARDFUNCTION or Standard_Function)
f[x :] or f(x :) is a function declaration on a variable x of undefined type 
f[x : Integer] or f(x : Integer) is a function declaration of an integer variable
a / b is division, such that x / x is undefined for x = 0
a // b is algebraically simplified division, such that x // x = 1 
x /. a -> b replaces occurrences of a in x with b (with priority of division so that in 4/.4 -> 5 gives 10. -> 5)
^ is exponentiation
a * b is multiplication, though a smart editor could allow blanks too if this can be made so
Result and Result[...] indicate the former result (% is percent and not "former result")
V is Or, & is And, => is Implies, ! or ¬ is Not. For example axiom p V !p. Here V is the logic symbol and not the letter v.
