4085
Cards used: 4000, 80 and 5 Expanded form: 4000 + 80 + 5 In words: four thousand eighty five
Why it happens: there is no hundreds card, because 4085 has 0 in the Hundreds place. When the three cards are laid on top of each other with their arrow heads in line, that empty place shows the 0 of the 4000 card.
Tip: we do not pick single digits. We pick one card for each place — Thousands, Hundreds, Tens and Ones.
