Place Value Online Math Tutoring
It means that each digit within a number represents a value depending on its
position. For example, in the number 452, the digit 2 would represent 2 units,
the 5 would represent 5 tens (or 50) and the 4 would represent 4 hundreds
(400). Moving from right to left, each digit is 10 times larger, or from left to right
, each digit in 10 times smaller. This is also true for decimal numbers. In order
to work out which value represents what, we can use a place value chart.
Example 1.Let’s use a place value chart to find out what all the numbers in 87 543 mean. To make it easier to put the digits in the right box, we can start by placing the unit in its box first, then moving left.
The 8 represents 80 000 The 7 represents 7 000 The 5 represents 500 The 4 represents 40 The 3 represents 3 
Example 2.Let’s try a slightly harder place value chart, with a number that has decimals. The number we’ll use is 76.23. After the units column, to the left we must put a tenths column, then a hundredths column etc. You can draw a decimal point between the boxes for units and tenths
The 7 represents 70 The 6 represents 6 units The 2 represents 2 tenths or 0.2 The 3 represents 3 hundredths or 0.03
