            Forming 3-Digit Numbers


            We have 900 numbers with three digits.

            100 is the smallest 3–digit number. 999 is the greatest 3–digit number.


            Let us form 3–digit numbers using 2, 5 and 6.

            With the given three digits, we can form six 3–digit numbers.

            To form 3–digit numbers with the given digits, we may put the digits 2,

            5  and  6  at  Hundreds–place,  Tens–place  and  Ones–place  turn  by  turn

            and get the different numbers, as 256, 526, 625, 265, 562 and  652.

            The greatest number is 652 and the smallest number is 256.

            Even and Odd Numbers


            Even  Numbers  :  An  even  number  is  a  number  that  can  make  a  pair.

            Numbers having 0, 2, 4, 6 or 8 at the ones place are even numbers.

            Odd Numbers : An odd number is a number that cannot be divided into
            two equal groups. Numbers having 1, 3, 5, 7 or 9 at ones place are odd

            numbers.
