Symbolic algebra software is a program, often accessible as an interactive environment, that is able to work directly with symbolic expressions (derivatives, integrals and so forth) and permits exact arithmetic (e.g. <tt>exp(-i*pi/2) = -i</tt>) as well as other formal operations that arise in domains like number theory, differential geometry, commutative algebra and so forth. Most such programs also permit the use of approximate numerical calculations using floating point numbers for handling problems that are analytically intractable. Some well-known symbolic algebra software packages are the commercial products [http://www.wolfram.com/mathematica/ Mathematica] and [http://www.maplesoft.com/ Maple], neither of which is available on Compute Canada clusters. An open source alternative, [https://www.sagemath.org/ SageMath], can however be used by loading the appropriate module: | Symbolic algebra software is a program, often accessible as an interactive environment, that is able to work directly with symbolic expressions (derivatives, integrals and so forth) and permits exact arithmetic (e.g. <tt>exp(-i*pi/2) = -i</tt>) as well as other formal operations that arise in domains like number theory, group theory, differential geometry, commutative algebra and so forth.
