Frequently asked questions
How does expanded form handle numbers with a zero digit, like 305? A zero digit contributes nothing to the sum, so 305 expands to 300 + 5, with the tens place simply omitted rather than written as "+ 0".
Does expanded form work for decimals too? The core version targets whole numbers place by place (ones, tens, hundreds); decimal place values would need a separate expanded-decimal-form treatment.
