Easy: Four-digit numbers
Expanded form writes a number as the sum of the values of its digits: 47,302 = 40,000 + 7,000 + 300 + 2. A digit 0 adds nothing, so it is left out of the sum, but going back to a number it must be written as a 0 to hold its place.
Write each number in expanded form, or as a number.
Tip: tick “Step-by-step answer key” in the generator to print each step for marking.
Write each nonzero digit's value: 300,000 + 5,000 + 90. The zeros are skipped because they add nothing.
Put each digit in its place and fill the missing places with zeros. 40,000 + 600 + 7 has no thousands or tens, so it is 40,607.
