Place Value
In our decimal number system, the value of a digit depends on its place, or position, in the number. Each place has a value of 10 times the place to its right.
A number in standard form is separated into groups of three digits using commas. Each of these groups is called a period.
When a number is written in this form, it is said to be in "standard form."
