Sage has implicit multiplication turned off by default, but lets you turn it on, and even lets you set the level of implicit multiplication you want, see this answer on Math.SE and the links there. http://math.stackexchange.com/questions/1186165/why-can-you-not-omit-the-sign-for-multiplication-in-sage-matlab-and-other/1186678#1186678 Other programming languages or software systems have different conventions. For example, Julia lets you write 5x or 2x^2. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
