Okay, let's pretend you are a young child who wants to learn about the Indian influence on Islamic science.
So, a long time ago, in a region called the Indian subcontinent, many people were practicing different religions and doing different things. Some of these people were really smart and came up with great ideas and inventions that helped them learn about the world around them.
One day, these ideas and inventions started to spread to other regions, including the region where Islamic people lived. The Islamic people were really impressed and started to learn from the Indians.
What kinds of things did they learn? Well, for example, they learned about math, science, and medicine. They learned about things like zero (which is a really important number!), the decimal system, and the concept of infinity. They also learned about how to use herbs and plants to make medicines that could heal people.
Over time, Islamic people started to build on these ideas and make their own discoveries. They combined Indian knowledge with their own ideas and created something new and unique.
So, in summary, the Indian influence on Islamic science was that the smart ideas and inventions from India spread to other regions, including Islamic regions. The Islamic people were impressed and learned from the Indians, which led to new discoveries and ideas.
