CONTENT

 

The numeric table is used to show the position of Numbers in the table. The table has various columns that are divided into units, tens, hundreds, thousands etc.

Numbers that are in single digit are said to be in UNITS

Examples of figures that are in digits are 0,1,2,3,4,5,6,7,8 and 9

Hence one single 5 = 5 units

Hence one single 7 = 7 units

Hence one single 0 = 0 units

Two digits figures are said to be in Tens. The first figure is said to be in Tens while the second figure is said to be in units

Examples of two digit figures are the following. Please note that the first figure is is tens while the second figure is in unit

Examples of figures that are in 2 digits are 20,14, 72,33,84,35,26,17,88 and 90

 

Hence  two digit number like 54 = 5 tens 4 units

 

Hence  two digit number like 55 = 5 tens 5 units

 

Hence  two digit number like 90 = 9 tens 0 units

 

Hence  two digit number like 72 = 7 tens 2 units

 

Hence  two digit number like 12 = 1 tens 2 units
