ACL2

Acl2 stands for "A Computational Logic for Applicative Common Lisp". It is a computer programming language and a system of tools used in mathematical reasoning. Acl2 is a logical language, which means it's a way of expressing and checking the correctness of logical statements. It is commonly used for proving things in mathematics, or making sure that computer programs are correct. Acl2 combines aspects of logic and programming to create a very powerful language. Acl2 can also be used to check things like the properties of mathematical objects, or the correctness of computer programs.
