Easy Multiplication trick
Method for multiplying numbers where the first figures are the same and the last figures add up to 10
FOR Example:-
Both numbers here start with 3 THEY ARE SAME and the last
figures (2 and 8) add up to 10
So we just multiply 3 by 4 (the nextnumber up) to get 12 for the first part of the answer.
And we multiply the last figures: 2 x 8 = 16
to get the last part of the answer. And 81 x 89 = 7209 We put 09 since we need two figures as in all the other examples
