Good catch. I'd suggest White Out above the exclamation point, but does anybody use typewriters anymore?

Don't you mean 6:599999999999999999999999999999999999?

Could someone explain 1, 3, 8, 9, and 11?

Ooo.. That's good.. I'm not sure if I can do most of that math
Quote: paisielloCould someone explain 1, 3, 8, 9, and 11?
1 = I have no idea, but typing "b prime sub l" into Google indicates that it is a common search term, and that it equals 1
3 = the HTML entity for the character '3'
8 = binary 1000 = 8 decimal
9 = I have no idea
11 = the '0x' indicates that what follows it is hexadecimal, and hex code 0B is 11 in decimal

9 = 21 using a base 4 system.

I don't understand 4.
I also don't understand 1, but maybe google will shed some light.
Every hour uses three 9's, except for 1 O:Clock. What am I missing? What does 1 have only two 9's? For example, they could have used 9^(9 - 9) for 1.

Or 9*9/9^2

It's a modular multiplicative inverse. You can't think of it as 0.5 mod 7. Like how (sin^-1)x isn't 1/(sinx).
Basically, solve for x where x=[1 to 7]: 2x = 1 mod 7
The only answer that fits is x=4. So 4 is the multiplicative inverse of 2 mod 7.

No, this uses a "2".Quote: chickenmanOr 9*9/9^2

I agree. Good solution.
