Place Value

The position of a numeral in a number represents the group to which it belongs. For example, in the number 145, 1 represents the hundreds group, 4 represents the tens group and 5 represents the units or ones group.

Now, here is a greater number:
xyz, 432, 819, 765

The place value of each numeral is given below,
5 is in ones place
6 is in tens place
7 is in hundreds place
9 is in thousands place
1 is in ten thousands place
8 is in hundred thousands place
2 is in millions place
3 is in ten millions place
4 is in hundred millions place

If the letters xyz are numbers then
z is in billions place
y is in ten billions place
x is in hundred billions place
(The trillions place value is for you to work on.)

When reading a number you always start from the first digit on the left, read the number and its position, and move on to the right until the last digit. Use a comma (,) or a space to separate each of the three digits from the right to make it easier when reading.

If xyz is 114, such that we have 114, 432, 819, 765 then it is read as "one hundred fourteen billion, four hundred thirty-two million, eight hundred nineteen thousand, seven hundred sixty-five".

Another example, we have 601, 073 then it is read as "six hundred one thousand, seventy-three".
