Can you give some context on how using Lean benefits?

In my understanding, proofs are usually harder to transcribe into Lean which is nobody _writes_ proofs using Lean.

What is a nlinarith?

nlinarith is a proof automation that attempts to finish a proof using the simplex method to find a linear combination of hypotheses and things that have already been proven, as well as some quadratic terms of them.
