Figured out how delayed my train was.

(It was a 19:07 train, which arrived at 19:35... that's a 28-minute delay!)

25*45 = 1125

I actually did that in my head quite quickly, using the Difference of Two Squares formula:

25*45 = (35 - 10)(35 + 10) = 352 - 102 = 1225 - 100 = 1125 :)

Does converting hexadecimal to binary and then from binary to decimal count?

00-B0-D0-63-C2-26
0000|0000 = 0
1011|0000 = 16+32+128 = 176
1101|0000 = 16+64+128 = 202
0110|0011 = 1+2+16+32 = 51
1100|0010 = 2+64+128 = 194
0010|0110 = 2+4+32  = 38

so 0-176-202-51-194-38 would be the official transcription of that MAC address into decimal.  as you can imagine... lots of math with each position from right to left being a doubling of the one before it.

1 0001
2 0010
3 0011
4 0100
5 0101
6 0110
7 0111
8 1000
9 1001
A 1010
B 1011
C 1100
D 1101
E 1110
F 1111

Added a couple of prices: £2.45 + £5.49 = £7.94.

(Turned out to be useless, because the £2.45 price wasn't even correct. It was actually £2.49, and I'd misheard it -_- !)
