Matlab is a computer program that helps people draw pictures and do math problems. Just like with paint, you can pick different colors and draw shapes on a picture with Matlab too.
But Matlab is also really good at doing math problems. If you have a bunch of numbers, you can use Matlab to add them together or find their average. It can also help you solve equations, like figuring out what x equals in a tricky math problem.
Think of it like a magical toolbox that can help you with your drawing and math homework!
