         This method of solving problem of multiply numbers between 11 and 19 like ...... 11×19, 12×15,15×16,19×15,15×15. This type problem solve by this shortcut tricks. There is some steps Step 1:- Aad the larger number to the right                 most digit of the other number Step 2:- put a 0 at the end of the step 1 Step 3:- multiply the rightmost digit of both                 original number Step 4:- add step 2 and step 3 Ex. 18 × 15 = 230 Step 1 :- 18 + 5 = 23 Step 2 :- 23 × 10 = 230 Step 3 :- 8 × 5 = 40 Step 4 :- 230 + 40 = 270 Ex. 18 × 18 = ____ Step 1 :- 18 + 8 = 26 Step 2 :- 26 × 10 = 260 Step 3 :- 8 × 8 = 64 Step 4 :- 260 + 64 = 324 Some problem there is show. So practice this problems

Some condition is satisfy for this problem like if two multiplication number ending is one required ex. 21×31 ,51×71,101×151 That type of problem this condition is satisfy for solve this some steps is apply Step 1:- multiply the leftmost digit Step 2:- add left most digit Step 3:- place the result from step 2. Next to               the result step 1 Step 4:-place the 1 next to the result step 3 Ex:- 51 × 21 = 1071        Step 1:- 5×2 = 10        Step 2 :- 5+2 = 7        Step 3 :- 10_7 .......107        Step 4 :-  107_1  So we have find answer that is 1071 If step 2 answer is two digit then  this digit leftmost digit add in the step 1 answers Ex . 71 × 151       Step 1 :-  7× 15=105       Step 2 :-  7+15=22       Step 3 :-. 105_22. Then left most digit of         ...

For solving this type of problem there is some tricks Step 1:- Add both digit of the two digit number Step 2:- place the result in between both digit This step is required for solving multiplication of two digit number by 11, let's give some example Ex. 56 × 11 =--- First step is add both digit of two digit number means 5+6=11. Then answer is 11 fined this digit (11) place in between 5 and 6 Means. 5_11_6 Like that but this is not answer. Now if adding is two digit find then one digit of left side of one digit add in first digit of left hand side (5+1)=6 then answer is 616 I have s

this is method of solving square number ending with 5 or last in 5 This method is applicable only this digit which last digit is 5. this is so easy method for solving square number So what happened in this  step 1:- multiply first digit by first digit plus one Step 2 :- write the number 25 next to the result from step 1 There is show some image for explained and I give some problems for solving ,solve by the method. and Be practice Solve this problem by using tricks
