Why is the number 6 so scared? Because 7 ate 9! In this section, we will be learning how to determine the value of digits in whole and decimal numbers. We will do this by figuring out the place, or position, of a digit in a number using the place value system. Each place, or position, in the place value system has a value of 10 times the place to its right. In this section, we will show the value of each digit in a number by expressing the number in words and by writing the number in expanded form.
