2015-05-26 11:38:05 +0200	asked a question	Solving system of inequalities in one variable I am probably missing something about how to use sage: If I run this: `x = var('x') a = var('a') solve([a*x>0,a>0],[x])` I get this results: `[[0 < x, a > 0], [x < 0, -a > 0, a > 0]]` However, I would expect something like: `[0 < x, a > 0]` What am I missing? Thanks
