Place Value

Throughout history, most (but not all!) human cultures have used a decimal number system, based on the number $10$ .

In our positional decimal notation, digits have different values depending on where they are placed . Each place value is $10$ times the place value to the right, and one-tenth of the place value to the left.

$\mathrm{96,548,327}$

This number has eight digits.

In the ones place is a $7$ , with the value $7\times 1=7$ .

In the tens place is a $2$ , with the value $2\times 10=20$ .

In the hundreds place is a $3$ , with the value $3\times 100=300$ .

In the thousands place is an $8$ , with the value $8\times 1000=8000$ .

In the ten thousands place is a $4$ , with the value $4\times 10,000=40,000$ .

In the hundred thousands place is a $5$ , with the value $5\times 100,000=500,000$ .

In the millions place is a $6$ , with the value $6\times 1,000,000=6,000,000$ .

In the ten millions place is a $9$ , with the value $9\times 10,000,000=90,000,000$ .

The total value of the number is the sum of all the place values:

$90000000+6000000+500000+40000+8000+300+20+7=96,548,327$
