Tutorial, Release 10.1
Sage is free, open-source math software that supports research and teaching in algebra, geometry, number theory,
cryptography, numerical computation, and related areas. Both the Sage development model and the technology in Sage
itself are distinguished by an extremely strong emphasis on openness, community, cooperation, and collaboration: we

ONEINTRODUCTION
This tutorial should take at most 3-4 hours to fully work through. You can read it in HTML or PDF versions, or from
the Sage notebook clickHelp, then clickTutorialto interactively work through the tutorial from within Sage.
Though much of Sage is implemented using Python, no Python background is needed to read this tutorial. You will
want to learn Python (a very fun language!) at some point, and there are many excellent free resources for doing so:
the Python Beginner"s Guide [ PyB ] lists many options. If you just want to quickly try out Sage, this tutorial is the place to start. For example:sage:2+ 2 4 sage:factor(-2007) -1 * 3^2 * 223 sage:A= matrix( 4,4,range (16)); A [ 0 1 2 3] [ 4 5 6 7] [ 8 9 10 11] [12 13 14 15] sage:factor(A.charpoly()) x^2 * (x^2 - 30*x - 80) sage:m= matrix(ZZ, 2,range (4)) sage:m[0,0]= m[ 0,0]- 3 sage:m [-3 1] [ 2 3] sage:E= EllipticCurve([ 1,2,3,4,5]); sage:E Elliptic Curve defined by y^2 + x*y + 3*y = x^3 + 2*x^2 + 4*x + 5 over Rational Field sage:E.anlist(10) [0, 1, 1, 0, -1, -3, 0, -1, -3, -3, -3] sage:E.rank() 1 sage:k= 1 /(sqrt(3)*I+ 3 /4+ sqrt( 73)*5/9); k36/(20*sqrt(73) + 36*I*sqrt(3) + 27)

sage:latex(k) \frac{36}{20 \, \sqrt{73} + 36 i \, \sqrt{3} + 27} 1.1Inst allation
If you do not have Sage installed on a computer and just want to try some commands, use it online at http:// sagecell. sagemath.org See the Sage Installation Guide in the documentation section of the main Sage webpage [ SA ] for instructions on in- stalling Sage on your computer. Here we merely make a few comments. 1.The Sag edo wnloadfile comes with "batter iesincluded". In other w ords,although Sag euses Python, IPython,
PARI, GAP, Singular, Maxima, NTL, GMP, and so on, you do not need to install them separately as they are
included with the Sage distribution. However, to use certain Sage features, e.g., Macaulay or KASH, you must
have the relevant programs installed on your computer already. 2.The pre-compiled binar yv ersionof Sag e(f oundon the Sag ew ebsite) ma ybe easier and q uickerto ins tallthan
the source code version. Just unpack the file and runsage. 3.If y ou"dlik eto use the Sag eTeXpac kage(whic hallo wsy outo embed the results of Sag ecomputations into a
LaTeX file), you will need to make SageTeX known to your TeX distribution. To do this, see the section "Make
SageTeX known to TeX" in the
Sag eins tallationguide
this link should tak ey outo a local cop yof the ins tallationguide). It"s quite easy; you just need to set an environment variable or copy a single file to a directory that TeX
will search. , where "$SAGE_ROOT" refers to the directory where you installed Sage - for example,/opt/sage-9.6. 1.2W ayst oUse Sag e
You can use Sage in several ways.
Notebook graphical interface:runsage -n jupyter; seethe Jup yterdocumentation on-line , Interactive command line:seeThe Interactive Shell,Programs:By writing interpreted and compiled programs in Sage (seeLoading and Attaching Sage filesand
Creating Compiled Code), and
Scripts:by writing stand-alone Python scripts that use the Sage library (seeStandalone Python/Sage Scripts).4Chapter 1. Introduction

1.3Longt ermGoals f orSag e
Useful: Sage"s intended audience is mathematics students (from high school to graduate school), teachers, and
research mathematicians. The aim is to provide software that can be used to explore and experiment with math-
ematical constructions in algebra, geometry, number theory, calculus, numerical computation, etc. Sage helps
make it easier to interactively experiment with mathematical objects.Efficient:Be fast. Sage uses highly-optimized mature software like GMP, PARI, GAP, and NTL, and so is very
fast at certain operations.Free and open source:The source code must be freely available and readable, so users can understand what the
systemisreallydoingandmoreeasilyextendit. Justasmathematiciansgainadeeperunderstandingofatheoremby carefully reading or at least skimming the proof, people who do computations should be able to understand
how the calculations work by reading documented source code. If you use Sage to do computations in a paper
you publish, you can rest assured that your readers will always have free access to Sage and all its source code,
and you are even allowed to archive and re-distribute the version of Sage you used. Easytocompile:SageshouldbeeasytocompilefromsourceforLinux,OSXandWindowsusers. Thisprovides more flexibility for users to modify the system.Cooperation:Providerobustinterfacestomostothercomputeralgebrasystems, includingPARI,GAP,Singular,
Maxima, KASH, Magma, Maple, and Mathematica. Sage is meant to unify and extend existing math software.
Well documented:Tutorial, programming guide, reference manual, and how-to, with numerous examples and
discussion of background mathematics.Extensible:Be able to define new data types or derive from built-in types, and use code written in a range of
languages.User friendly: It should be easy to understand what functionality is provided for a given object and to view
documentation and source code. Also attain a high level of user support.1.3. Longterm Goals for Sage 5

TWOA GUIDED TOUR
This section is a guided tour of some of what is available in Sage. For many more examples, see "Sage Constructions",
which is intended to answer the general question "How do I construct ...?". See also the "Sage Reference Manual",
which has thousands more examples. Also note that you can interactively work through this tour in the Sage notebook
by clicking theHelplink.(If you are viewing the tutorial in the Sage notebook, pressshift-enterto evaluate any input cell. You can even edit
theinputbeforepressingshift-enter. OnsomeMacsyoumighthavetopressshift-returnratherthanshift-enter.) 2.1Assignment, Eq uality,and Arithme tic
With some minor exceptions, Sage uses the Python programming language, so most introductory books on Python will
help you to learn Sage. Sage uses=for assignment. It uses==,<=,>=,Tutorial, Release 10.1
(continued from previous page) True sage:3^2*4+ 2 %5 38The computation of an expression like3^2*4 + 2%5depends on the order in which the operations are applied; this is
specified in the "operator precedence table" inArithmetical binary operator precedence. Sage also provides many familiar mathematical functions; here are just a few examples:sage:sqrt(3.4)1.84390889145858

may hold values of any Python type within a given scope:sage:a= 5 # a is an integer sage:type(a)The C programming language, which is statically typed, is much different; a variable declared to hold an int can only
hold an int in its scope.8Chapter 2. A Guided TourTutorial, Release 10.1
