Today I was reading the wikipedia entry for sage (http://
en.wikipedia.org/wiki/Sage_%28mathematics_software%29), and decided to
try the first example :
sage: show(solve(a*x^2 + b*x +c == 0, x ) [0])
Wikipedia proposes to write this :
x,a,b,c = var('x,a,b,c')
You have to "declare" the mathematical variables before to use them.
