Place Value
Every number can be formed using
ten digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The value of a digit depends on
its place in the number. This is what is known as place value.
In the number system we use the place value is based on groups of tens.
Ones:
1 2 3 4 5 6 7 8 9
Tens:10 20 30
40 50 60 70 80 90
Hundreds: 100 200
300 400 500 600 700 800 900
Thousands: 1,000 2,000
3,000 4,000 5,000 6,000 7,000 8,000 9,000

- Our number system is grouped into
periods - ones - thousands - millions - billions
- Each group has three divisions
- ones - tens - hundreds
- The number above is read as: three
million six hundred twenty-five thousand one hundred ninety-seven.
- This number above can be written
in expanded notation in three ways:
|
3 million + 6 hundred thousand
+ 2 ten thousands + 5 one thousands + 1 hundred + 9 tens + 7 ones
(3
x 1 000 000) + (6 x 100 000) + (2 x 10 000) + (5 x 1 000) + (1 x 100)
+(9 x 10) + (7 x 1)
3 000 000 + 600 000 + 20 000 + 5 000 + 100 + 90 + 7
