Mathematics in medieval Islam

Okay kiddo, let me try to explain mathematics in Medieval Islam in a way that you can understand. So, in the time long ago when knights were around, people in some parts of the world were studying math; that's what we call Medieval Islam. Islam is a religion followed by many people in different parts of the world.

Now, these people loved math and they made lots of discoveries that we still use today. They invented new ways to write and calculate numbers, such as the number zero that we use all the time. Can you imagine not having a zero? It would make math really hard!

They also studied geometry, which is like shapes and lines, and they discovered new ways to measure them accurately. This helped people in different trades and professions, like architects and builders.

One famous mathematician from this time was named Al-Khwarizmi. Don't worry, you don't have to remember that name! He wrote a book called "Al-jabr w'al muquabalah" which means "The Compendious Book on Calculation by Completion and Balancing." That's a really big name, right? But in that book, he explained how to solve equations, or ways to solve math problems that we still use today.

So, in Medieval Islam, people loved math and they made many important discoveries that still help us today, like zero, geometry, and equations. It's pretty amazing, right?
