In the number 10 we have one lot of ten and zero ones.
In the number 23 we have 2 lots of ten and 3 ones. 20 + 3 = 23
In the number 59 we have 5 lots of ten and 9 ones. 50 + 9 = 59
In the number 136 we have 1 lot of 100, 3 tens and 6 ones. 100 + 30 + 6 = 136
For bigger numbers we use more and more columns. Each column is ten times bigger than the column to its right.
Example 1:
Write down the value of the 4 in the number 9487.
9487 = 9000 + 400 + 80 + 7
The 4 is worth 400.
Example 2:
Write down the value of the 8 in the number 180950.
180950 = 100000 + 80000 + 900 + 50
The 8 is worth 80000.
