Enjoy maths !!
These days, we tend to overlook the maths easily.
Here is why we should not. Maths has some beautiful characters, when manipulated properly, they look extremely symmetric, ornamental, attractive, also encouraging you to think why and how and explore further. You may like to forget the maths since you feel day by day it is becoming less useful (what is there to count? - everything that goes up, comes down - Sensex(?)), but please treat this entertainment as new use of maths.
1 x 8 + 1 = 9
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 = 9876
12345 x 8 + 5 = 98765
123456 x 8 + 6 = 987654
1234567 x 8 + 7 = 9876543
12345678 x 8 + 8 = 98765432
123456789 x 8 + 9 = 987654321
1 x 9 + 2 = 11
12 x 9 + 3 = 111
123 x 9 + 4 = 1111
1234 x 9 + 5 = 11111
12345 x 9 + 6 = 111111
123456 x 9 + 7 = 1111111
1234567 x 9 + 8 = 11111111
12345678 x 9 + 9 = 111111111
123456789 x 9 +10= 1111111111
9 x 9 + 7 = 88
98 x 9 + 6 = 888
987 x 9 + 5 = 8888
9876 x 9 + 4 = 88888
98765 x 9 + 3 = 888888
987654 x 9 + 2 = 8888888
9876543 x 9 + 1 = 88888888
98765432 x 9 + 0 = 888888888
Brilliant, isn't it?
And finally, take a look at this symmetry:
1 x 1 = 1
11 x 11 = 121
111 x 111 = 12321
1111 x 1111 = 1234321
11111 x 11111 = 123454321
111111 x 111111 = 12345654321
1111111 x 1111111 = 1234567654321
11111111 x 11111111 = 123456787654321
111111111 x 111111111=12345678987654321
How about the table of '9'.
9 X 01=09=(0+9)=09
9 X 02=18=(1+8)=09
9X03=27=(2+7)=09
9X04=36=(3+6)=09
9X05=45=(4+5)=09
9X06=54=(5+4)=09
9X07=63=(6+3)=09
9X08=72=(7+2)=09
9x09=81=(8+1)=09
9x10=90=(9+0)=09
