❓ Frequently Asked Questions (FAQs)
1. What are large numbers?
Large numbers are numbers used to represent very big quantities such as population, distances, money, and scientific data.
2. Why do we use commas in large numbers?
Commas make large numbers easier to read and understand.
3. What is the difference between face value and place value?
Face value is the digit itself, while place value depends on the digit's position in the number.
4. What is Computational Thinking?
Computational Thinking is a problem-solving approach that involves decomposition, pattern recognition, abstraction, and algorithm design.
5. Why are large numbers important in AI?
AI learns from huge amounts of data. Large numbers help AI process information, recognise patterns, and make accurate predictions.
