The code for an specific field —i.e. arithmetics— is encapsulated in a single unit called a Fōrmulæ **package**.\n\nThis repository contains the source code for the **algebra package**. It contains functionality tu perform algebraic expression simplification.\n\nNotice that creating a complete algebra system is not a trivial job. For now, this package includes a minimal set of operations, enought to perform operations with complex arithmetic.\n\nThe GitHub organization [formulae-org](https://github.com/formulae-org) encompasses the source code for the rest of packages, as well as the [web application](https://github.com/formulae-org/formulae-js).\n\n\u003c!--\nTake a look at this [tutorial](https://formulae.org/?script=tutorials/Arithmetic) to know the capabilities of the Fōrmulæ arithmetic package.\n--\u003e\n\n### Simplifications ###\n\n* Double negatives: $--x = x$\n* Negative of an addition: $-(a + b +c) = -a - b - c$\n* Negative of a multiplication: $-(abc) = (-1)abc$\n* Addition of an addition: $x + (a + b + c) + y) = x + a + b + c + y$\n* Multiplication of mutiplication: $x(abc)y = xabcy$\n* Multiplication of negatives: $a(-b)c = (-1)abc$, $(-a)(-b) = ab$\n* Multiplication distributes over addition: $a(x + y) = ax + ay$\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fformulae-org%2Fpackage-algebra-js","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fformulae-org%2Fpackage-algebra-js","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fformulae-org%2Fpackage-algebra-js/lists"}
