MULTIPLY NUMBER BETWEEN 11 AND 19/ SHORT TRICKS OF MULTIPLICATION

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

MULTIPLY TWO DIGIT NUMBER HAVING SAME TEN DIGIT AND ONCE DIGIT SUM IS 10

For solve this problem some condition is required that is

1. First left one digit should same 
2. And one right digit should sum is 10 of two digit

Ex. 21×29,35×35,43×47,42×48,98×92,84×86

Some steps are satisfy for this math short trick

Step 1 :- Multiply the first digit by the firs digit plus one 

Step 2 :- Multiply the rightmost digit ( if the result is single digit put a 0 infront of it )

Step 3 :- place the result from step 2 next to the result from step 1

Ex. 54 × 56 = 3024

Step 1 :- 5×(5+1) = 5×6 

                              = 30

Step 2 :- 4 × 6 = 24

Step 3 :- 30_24 

            = 3024

Ex. 69 × 61 = 4201

Step 1 :- 6 × (6+1) = 42

Step 2 :- 9 × 1 = 09

               (When the result is single digit then put 0 infront of it)

Step 3 :- 42_01 = 4201

   Try some problems. And use this trick but remember condition

MULTIPLY TWO DIGIT NUMBER ENDING 1/ GREAT TRICK IN SECOND

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                            step 2 that is 2 add in 105
                       =105+2
                       =107
                       =107_2
                       =1072
      Step 4 :- 1072_1
                      10721
I have show some problems for practice try this

FINDING MULTIPLY TWO DIGIT NUMBER BY 11 / SOLVE IN 2 SECOND

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 show some problem solve this problem by this tricks

FINDING SQUARE NUMBER ENDING WITH 5

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

HOW TO BECOME BRILLIANT IN MATH

      Many people they are not become loss in math. they feel like math is bad and it's so irritated. and some people is bored. but they want to improve our math. I tell you math is best subject but just need of to know of math
  now you have to choose one aim about math that is
First is you know about math and second things is you know about math

knowing to the mind 

       when you study of math but we feel bored and irritated. some people feel like just live it. when that type of feeling inside your mind then play with your mind na shive the right way to the mind ( just convert for math only )

 practice

       Math  have need practice, if you know math then math will give you way. and give the time to math and math give you time ( because of math study become easy and for math study time is save. it's so easy some time some problem is hard that time you left your problem of math but remember that time just focus on your practice and give the way to solution

Try different type of problem

      when you solve some problem of math but some problem is hard. it's mean is additional tricks is apply so don't fear about problem and solve by different tricks. and solve some problem of your own way. not important your solution is wrong, just need of try

SQUARE NUMBER BETWEEN 100 AND 109/ SOLVE IN SECOND

This method use only for square number between 100 and 109 that is square of 100,101,102,103,104,105,106,107,108,109 etc.
Only find that square
Step of finding square of 100 and 109.
Step 1:- Add the number. to the once digit of leftmost one digit
Step 2 :- square the once digit number ( if the result is single digit put the 0 in front of it)
Step 3 :- place the result first step 1 and after step 2.

Ex. 108 square
Step 1 :- 108+8=116
Step 2 :- 8 square = 64
Step 3 :- 116_64
             = 11664

Ex 2. 102 square
Step 1 :- 102+2=104
Step 2 :- 2 square = 04 (because step 2 result is single digit so put 0 in front of the result))
Step 3 :- 104_04
            = 10404
 Practice of some problem and be better
