[QUOTE=Uncwilly;324577]Yesterday was a busy day for me, but I was going to post:

1+12=13[/QUOTE]Equivalently, 12+1=13 in little-endian format.



Today, 13*1 = 1*13=13

Uncwilly 2013-01-13 15:28

[TEX]\frac{13}{13}=1[/TEX]

(13-14)+2-0 = 1

Since we're only allowed one entry here per day,
with one-ups-manship to be avoided, I'll leave unnoticed
the fact that

21+3 = (1+1),4 + 0

where , is concatenation.

Today has been:
13131 = YYMDD
or
31113 = DDMYY

both palindromes.

[QUOTE=ATH;319803]Today is my birthday. I was born in 19xx. My age is: xx div 2[/QUOTE]

Not possible on November 28th, 2012.

Your birth year would have to be 1974-2/3rds and your age would have to be 37-1/3rd. But if your age was 37-1/3rd, it would not be your birthday.

...or if your birth year was 1975, your age would be 75 / 2 = 37.5...once again it wouldn't be your birthday.

"Div" is integer division, smartass :mad:

75 div 2 = 37

Nice name calling.

It depends on the audience. If you're not a programmer, which 90+% of the population and likely 50+% of this forum is not, div is just short for divided by. :smile:

Today 13, 2, 1
1321 is prime

div is, where I come from, a divergence operator on a [FONT=CMR12]differentiable vector field.[/FONT]
[FONT=CMR12]The results is a [FONT=CMR12]scalar field.[/FONT]
