Proof assistant

A proof assistant is like a machine that helps people make sure they are right when they say something is true.

Just like when you do a puzzle or play a game, you need to follow certain rules to make sure you have solved it correctly. A proof assistant is like those rules, but for people who are trying to prove that something is true in math or science.

Think of it this way: when you write a math problem on a piece of paper, you need to show how you arrived at the answer step by step. A proof assistant is like a really smart computer program that checks each of those steps to make sure they are correct. It can even help you figure out if there is a mistake in your reasoning, and suggest ways to fix it.

This is important because it helps us be sure that what we say is true is actually true. It's like having a superhero on your team that makes sure you don't make any mistakes with your math!
