Mathematics Tricks and Tips : Trick 1 : Phase 2

 Trick 1: Phase 2

 (N₁ > 100 & N₂ <100 or Vice versa)

Multiply:

         107            by        98

Step 1: Find the difference of the numbers by         100 with signs.

                        107 | +7

                          98 | -2

Step 2: Multiply the differences

                        107 | +7

                          98 | -2

                                  -14

Step 3: Cross Add the 1^st number with difference of the other.

                 

                             107 | +7

                               98 | -2

                 (107 + (-2))  -14

                  = 105 – 14

Step 4: Subtract 1 from the sum and subtract the multiplicand from 100.

                (105 – 1) (100 – 14)

    Answer =     10486

        And here is your answer

Mathematics Trick 1 : 3 digit Multiplication

Trick 1: Phase 1 (n and n₁ > 100)

Having Problem in Multiplication? Getting less time for solving larger problems? Read it and get to Know about this simple VMT (Vedic Mathematics Trick)

Solve: 105 X 107 in 10 seconds……

  Impossible?

  Not at all.

You don’t need to solve it in a large method. Just a 7 second method with steps.

1.          Write the multiplicands in the correct form

                105

             X 107

2.          Subtract each no. from 100 and write the difference with sign.

                105| +5

             X 107| +7

3.          Multiply the differences in 2 Digits (When Multiplication more than 3 DIGITS will be published later)

                105 | +5

             X 107 | +7

                           35

4.          Cross add the 1^st No. with the difference of the other.

                 105 | +5

             X 107 | +7

            (105 +7) 35

       =        11235

5.         And here your result is.

6.          You can check this with any 3 digit nos. but when the multiplicands of differences is 3 digit, take a carry to the left digit and leave other digits same.

          Eg.   110   +10

                  115   +15

                  125           +150

                      = 12650
