Defining relationship
Pack the place-value parts into their digit slots; use zero to hold an empty slot.
In standard numeral form, one base-ten numeral gives the whole value; every digit occupies its matching place. This contrasts with spelling the number in words or breaking it into an expanded sum.
six thousand two hundred four
The 0 holds the tens place; without it, 624 names a different number.
What it means
Expanded form spreads a number into place-value parts. Standard numeral form packs those parts back into one numeral. A missing place still needs a zero, because each digit’s position tells its value.
Remember it
Pack the place-value parts into their digit slots; use zero to hold an empty slot.
Example
Write 6,000 + 400 + 9 in standard numeral form. The hundreds and tens slots are empty, so the numeral is 6,409.
Watch for
In UK and Singapore secondary mathematics, “standard form” often means scientific notation. This card owns the elementary base-ten numeral sense.
Common mix-up

Exact meaning
