... let me also try...

2587 (is that divisible by 13 ?) + 13 = 2600 = 200 x 13

is that correct??

is that ALL i had to do?

2600 yeah!!

i love this number!!!

its nice... let me try some more...

2600 + 13 = 2613

2613 + 13 = 2626 (hmmm... intersting number again!)

2626 + 13 + 13 + 13 + ..... 13 + 13 (N times) = (2 x 101 + N) x 13

ooooohhhh

**oh!** my previous sum is wrongly typed as **2873** whereas it actually equals **2899**

**2899+13=2912**
