The Foundation of All Numbers
Imagine you have £537 in your wallet. The first digit (5) represents £500 - five hundred pounds! The last digit (7) represents just £7 - seven pounds. Same digit (5 and 7), but completely different values based on their POSITION. This is the magic of place value - it's what makes our entire number system work, and it's the foundation you need to master before tackling any other maths topic.

What is place value?
Place value is the value a digit has because of its position in a number. Each column is worth 10× the column to its right.
How do you order whole numbers?
1. Compare number of digits (more digits = bigger)
2. If same digits, compare left to right
3. Find first column where digits differ
4. Bigger digit in that column = bigger number
