SageMath in Neon

[GreyGeek]

I downloaded sagemath version 7.4 for Ubuntu from their website:

wget http://mirrors.xmission.com/sage/lin...x86_64.tar.bz2

After I unzipped it and ran tar

bunzip2 ./sage-7.4-Ubuntu_16.04-x86_64.tar.bz2
tar -xvf ./sage-7.4-Ubuntu_16.04-x86_64.tar

I then ran the sage binary. If failed reporting

I noticed the mislabel (7.5 instead of 7.4) but I knew that 7.3 installed in 16.04 without problems so I downloaded and installed it.

wget http://mirrors.xmission.com/sage/lin...x86_64.tar.bz2

I unzipped and installed it and it works fine.

A tour of SageMath is here.

I just sent a linky to a calculus friend of mine. thanks. I'll probably use this myself next semester but after that, Obama sent me back to biology! lol
but, hey, great linky!

Great app. When sage starts up I enter "notebook()" and it fires up FireFox and presents a Mathmatica type interface. Works slick!
