Litex: Formal math for everyone – set theory examples with Lean comparison

https://litexlang.com/doc/How_Litex_Works/Litex_vs_Lean_Set_Theory_Examples
2•litexlang•1h ago

litexlang•1h ago
[Litex](https://litexlang.com) is a simple open-source computer language for mathematical proofs. Anyone can have a rough understanding of Litex in 2 hours.

Although it is not yet ready for production use, it is already powerful enough to formalize set theory and basic logic, which is enough for most daily mathematical proofs. Visit [Set Theory Examples](https://litexlang.com/doc/How_Litex_Works/Litex_vs_Lean_Set_...) for more examples.

Star the repo [here](https://github.com/litexlang/golitex) to support Litex, and join our [Zulip community](https://litex.zulipchat.com/join/c4e7foogy6paz2sghjnbujov/) to give us feedback and suggestions!
