Beauty 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

Maths problem at Verizon Wireless

This is an absolutely absurd conversation, in which representatives of Verizon Wireless are making fools of themselves.



The problem is this: The caller has been quoted a rate of 0.002 cents/kb for internet traffic in Canada (and this is readily accepted by Verizon Wireless), but when he gets the bill, he is charged 0.002 dollars/kb. The really amazing part of the conversation is when Verizon Wireless makes this calculation:
0.002 c/k * 35,893 k = 71.79 dollars
without understanding that the caller has a problem with the sudden change from cents to dollars...

Would you buy shares in a company that don't know the difference between cents and dollars?

I must add that the tape may be a hoax, as it seems incredible that Verizon Wireless could be this stupid.

I have contacted Verizon Wireless for their comments, but I have not had an answer so far. I will update this story if I receive a comment.

(For the record: the "stupid" part is not the part of not knowing math - it's setting people who don't know math to be the company's representatives to discuss maths problems.)
