There are always some fun way to deal with maths operation. Read on .....
Multiplication produces big numbers. It seems fearful compared to the simple addition or subtraction, but hold on.
Maths multiplying can be fun and interesting, besides being quickly done.
Take the case of 23 x 11 = 253.
If we reverse the "2" and "3" in the number 23, we get "32".
Now if we multiply this newly reversed "32" by 11, we will get 32 x 11 = 352.
The result is the reverse of that for 23 x 11 ! AMAZING isn't it ?
Try another product (multiplication):
421 x 11 = 4631. ===> 124 x 11 = 1364 (again the maths result is the reverse!)
NOTE: This maths outcome is valid only when the number (integer) is multiplied by 11.
Why is it so? Think about it. It involves some algebra, for a hint.
