With the digits 1 and a pair of we will make the numbers 12 and 21.

Face worth is the worth of a digit in a quantity.

So, the digit 1 has the identical face worth in each the numbers `12 and 21.

 Equally, the digit 2 has the identical face worth within the numbers 12

We write 12 and 21 through the use of ones and tens as:

Within the quantity 12, the worth of two (i.e., 2 ones) is lower than
the worth of 1 (i.e., 1 ten)

(ii) 602 means:  6 a whole lot  0
tens  and  2 ones =  600   +    00   +    2

                                                             602      =  600    +   00   +    2

Within the quantity 602, the place worth of 6, 0 and a pair of are 600, 00
and a pair of respectively.

(iii) 278 means:

   2 a whole lot   7
tens  and   8 ones   =   200  
+   70    +    8

                                             278    =   200   +   70   
+    8

and eight respectively.

(iv) 777 means:  7 a whole lot 7
tens  and seven ones  =  700   +  70     +   7

                                                             777      =  700   +  70    
+   7

Within the quantity 777, the place worth of seven, 7 and seven are 700, 70
and seven respectively.

(v) 63 means: 0 a whole lot  6
tens  and  3 ones    =   000   +   60   +    3

                                                              63       =   000   +   60   +    3

Within the quantity 63, the place worth of 0, 6 and three are 000, 60
and three respectively.

Subsequently, the place worth of a digit in a quantity is the
worth of the place which it has within the quantity.

Within the quantity 549,
the place worth of 5 is 500, of 4 is 40 and 9 is 9 as 5 occupies the place of
