Place valueIndividual digits when used in a combination help you build numbers. Place value assigns each digit a greater or lesser value dependingupon where it appears in a number. Each place in a number is TEN TIMES greater than the place value to its immediate right.Although the digit 0 adds no value to a number, it can act as a placeholder. When a 0 appears to the right of at least one non-zero digit, it%u2019s a placeholder. Placeholders are important for giving digits their proper place value. When a 0 isn%u2019t to the right of any nonzero digit, it%u2019s a leading zero. Leading zeros are unnecessary and can be removed from a number.For example: in the number one hundred two: 102zero is a placeholder in the tens place.For example: when we write the number one hundred forty two. We don%u2019t need to write it 0142.We write it 142.Here is a chart to show the place value of numbers:millionsthousandsoneshundredmillionstenmillionsmillionshundred thousandsten thousandsthousandshundredstensonesPractice:Place the number 7,521 in the table to show the value of the digits. Then write the number in expanded form. For example the expanded form of 432 is 400+30+2=432 That shows how you form the number.millionsthousandsoneshundredmillionstenmillionsmillionshundred thousandsten thousandsthousandshundredstensonesexpanded form:________________________________________________________________________Place the number 040,120 in the table to show the value of each digit.
