How do you write 1987 in expanded form?

Answer 1

1,000 + 900 + 80 + 7.

Expanded form is a way to write numbers by showing the value of each digit. In other words, expanded form is the method of pulling a number apart and expressing it as a sum of the values of each digit.

The best way to identify the expanded form of a number is to simply write the number in words, which separates them in this way. Each number in the expanded form has only one non-zero digit, and zeroes.

One thousand nine hundred eighty seven is in four parts: One thousand, nine hundred, eighty, and seven.

Now express this as a sum of digits.

1987= 1,000 + 900 + 80 + 7.
