Step 1 of 3
A box holds 100 pencils. Aoife's school orders 36 boxes.
How many pencils is that?
The school orders 3600 pencils.
The key insight: The digits move, not the number of zeros you write - count the zeros in 10, 100 or 1000 to know how far.
Common mix-up: 36 × 100 = 360. That moves the digits only one place. Multiplying by 100 moves them two places.
