building mathematical libraries and stating and proving mathematical theorems. From that perspective, the point of Lean is to implement a formal axiomatic framework in which one can define mathematical objects for mathematics, the CIC is much more than a programming language. One can define all kinds of mathematical objects: number sys- tems, ranging from the natural numbers to the complex numbers; algebraic types alongside other mathematical objects, and write programs alongside mathematical proofs. Terms in the Calculus of Inductive Constructions are therefore used to represent mathematical objects, programs

For example, the mathematical and coding abilities of our model can keep improving over a longer period of training steps. Therefore

computational methods to establish claims that are expressed in precise mathematical terms. These can include ordinary mathematical theorems, as well as claims that pieces of hardware or software, network and software systems in mathematical terms, at which point establishing claims as to their correctness becomes a form of theorem proving. Conversely, the proof of a mathematical theorem may require a lengthy verifying that the computation does what it is supposed to do. The gold standard for supporting a mathematical claim is to provide a proof, and twentieth-century developments in logic show most if not all

illustrations and special effects. 4.1.6. OpenOffice.org Math You can use Math for creating and editing mathematical equations by using a graphic user interface or by directly typing the formula into the equation OpenOffice.org Calc provides you with over 300 functions for financial, logical, statistical, mathematical and banking operations. This enables you to create formulae to perform complex calculations on formatted table with very little effort. Figure 4.31. The Formatted Table Entering Values and Formulas. A formula is a spreadsheet function, complete with arguments, entered in a cell. All formulae

duplication: • Compiler for Haskell-like recursive equations, we can use it to write proofs. • Mathematical structures (e.g., Groups and Rings) are first-class citizens. • Some references: • In praise Dan Suciu University of Washington https://arxiv.org/pdf/1802.02229.pdf Mathlib The Lean mathematical library, mathlib, is a community-driven effort to build a unified library of mathematics formalized Mathematics?
