Day 2 · Reading, Writing & Expanding Large Numbers

3,247,825 is read as "three million, two hundred forty-seven thousand, eight hundred twenty-five" — in expanded form: 3,000,000 + 200,000 + 40,000 + 7,000 + 800 + 20 + 5.

9,000,004 is read as "nine million, four" — notice there are no hundred-thousands, ten-thousands, thousands, hundreds, or tens at all.

Activity: Try writing a 7-digit number you see around you, like a country's population, in expanded form.
