Just downloaded sage-8.0-Debian_GNU_Linux_8-x86_64.tar.bz2. Seems to be working well. Great work as always!
Trying to solve simultaneous equations. Get error "TypeError: 'tuple' object is not callable."
Found exactly the examples I needed in Basic Algebra and Calculus. Solving Equations (online Sage reference). Copied and pasted Jason Grout's example and also the examples above it. Get error message "TypeError: 'tuple' object is not callable." in notebook() , but examples work in terminal.
Here is one of the examples that gives the error in notebook() (but works in terminal). sage: x, b, c = var('x b c') sage: solve([x^2 + b*x + c == 0],x)
What am I missing here?
Any ideas? Thanks.
