How to write and work electronic mathematical text without WYSIWYG software or LaTeX? This memo aims at proposing MathSAN, an acronym for Mathematics with Symbolic Ascii Notation, focusing on mathematical symbolic or semantic rather than typographic rendering: PDF memo, text memo.
Samples:
- A .i B := {x: x .e A and x .e B }
- sum[ i .e NAT ; 1<= i <= n ] = n*(n+1)/2
- der[ x**3*y**2 ; x.2 ; y ] = 12*x*y
- int[ x**2*dx ; a <= x <= b] = (b**3 - a**3)/3
