The Rule of 11

Most of us knows this already but for the ones who don't here it is...

11 being multiplied by 11, 12, 13, 14, 15, 16, 17, 18, 19

The answers are 3 digits...do you see the answer?

11x11=_ _ _ ...do you see the 1st and last digit (answer)? Here it is...
11x11=1_1 ...what would be the 2nd digit? How to get it? Just add 1+1=2...
11x11=121 ...let us try the next one without using calculator...

11x12=132... 1st digit is 1, 3rd digit is 2, and add 1+2 to get the 2nd digit
11x13=143... 1st digit is 1, 3rd digit is 3, and add 1+3 to get the 2nd digit
.
.
.
11x18=198...you should be able to get the answer mentally...

now the tricky one 11x19...since 9+1=10, 1 will be added to the 1st digit, middle will be 0 and the third digit will still be 9...so,

11x19=209!

This is just one of the short hand for computations...
Just like a book, where we read amazing stories and poetry, Mathematics has a story to tell...

It tells about us...our existance...our role in the universe...and the universe itself...We have only see and heard small piece of the increadible, amazing stories and poetry of the language of mathematics...

As we continue to decode and discover the language of mathematics, let us play and enjoy the ones that we could understand...
