log base e of 55 is too big for 4, should be 54.5981500331

as

2.718281828459045235 ^ 4 is 54.5981500331

Ten is the the acceleration of Earth's gravity, 9.82 m/s/s. Some versions of this clock have it written as

so it equals 10 exactly.Eleven is written in hexadecimal. In decimal, we have numbers 1 to 9, but in hexadecimal, as well as 1 to 9 there's 'a' to 'f' so you can keep counting: a equals ten, b equals eleven and so on. The zero at the front of '0b' doesn't make any difference here. It's just like writing the number three (in decimal) as 03.

Hi Agnishom;

Nice clock! So far nobody has argued with 7 o'clock.

I want that it's so cool!

Here's an explanation for younger kids (like me):

1: The tangent of a 45 degree angle is 1.

2: The square root of 4 is 2. (2 x 2 = 4)

3: If you round pi, (3.141592653589796264) you end up with 3. (1<4.)

4: The logarithm of 55 is 4.

5: x^2=3^2+4^2. 3 x 3 = 9. 4 x 4 = 16. 16 + 9 = 25. 5 x 5 = 25.

6: The factorial of 3 is 6.

7: If you round 6.9, you get 7.

8: 16/2=8

9: 3 x 3 = 9.

(For 10 and 11, look at the explanations above.)

What is 12?

hi

5: x^2=3^2+4^2. 3 x 3 = 9. 4 x 4 = 16. 16 + 9 = 25. 5 x 5 = 25.

Strictly it should be

root(3^2 + 4^2)7: If you round 6.9, you get 7

no rounding needed. That's 9 recurring there.What is 12?

that's 12 in binary (base 2)

I think you have it, but take a look at

I was talking about 6.9999.... which is exactly 7 and not a round-off of it

Proof:

Let x = 6.999....

Now, 10x = 69.99999....

Subtracting those equations, 9x = 63

Therefore, x = 7

Thus, 6.999... = 7 [Q.E.D]

I get it... just like 1/3 is never exact, it's 3.333333333 but then it would have to be the only 1/3. Is that it?

Yes, its like that ... "the recurring decimal"

Note that 1/3 = 0.333... and not what you wrote

The 5 is the best one.
