MULTIPLY NUMBERS FROM 101 THROUGH 109
      In this case the examples would be:-
         101x101
         104x107
         1 05 x105
        106x108
        109x109
And so on----
The total examples will be 45.
Procedure:-
•  The answer will be a five digit number beginning with 1.
•  The next two digits of the answer will equal the sum of ones digits.
•  The last two digits of the answer will equal the product of the ones digits.
Let’s use the trick.
Consider the problem: 102x107.
Step1:- Begin the answer with 1 ---.>   1
Step 2:-Add the ones digits    ------>2+7= 09.
Step 3:- Multiply the ones digits --->2x7=14.
Step 4:-Combine the amount from steps 1,2.and3 writing from left ------>10,914.
Answer 10,914.
Let’s try one more example.
109x105
Step 1:-Begin the answer with 1------------ .>1
Step 2:- Add the ones digits----------- ----->9+5=14.
Step 3:- Multiply the ones digits----------->9x5=45.
Step 4:-Combine the amounts for the steps 1, 2, and 3 .Writing from left to right----->11,445.
Answer is 11,445.
Note :-the sum or the product of ones digits is written in two  ,digits as01,02,03,04,05,06,07,08, and 09.
