    නියමයි.කියලා වැඩක් නෑ

    Thanks :)

    the oct 31 = dec 25 joke is a weird mathematical joke.
    oct = octal
    dec = decimal

    octal has base 8 and decimal has base 10.
    so 31 can be written like this in octal (3 x 8 + 1) = (2 x 10 +5) = 25 in decimal. i don't know if this explains well.i don't even know much about these bases things. simply,

    if you wanna write 31 in octal.easiest way is seperate the two digits like (3 1) and then multiply the 1st digit (eg: number 3 of 31) by 8 (because octa means 8 and it has base 8) and add + the other digit (eg: number 1 of 31) and you get something like this [3 x 8 + 1] this equals 25

    25 in decimal can be written in the same way but the base is 10. [2 x 10 + 5]

    basically 31 in octal equals to 25 in decimal. so OCT 31 = DEC 25

    Got it :yes::yes:

    The humor lies in the fact that Halloween occurs on October 31 and Christmas occurs on December 25, thus equating "oct" in October and octal, and "dec" in December and decimal.

    A mathematical joke is a form of humor which relies on aspects of mathematics or a stereotype of mathematicians to derive humor. The humor may come from a pun, or from a double meaning of a mathematical term. It may also come from a lay person's misunderstanding of a mathematical concept. These jokes are frequently inaccessible to those without a mathematical bent.

    (Possibly like me cause I still don't get it LOL)

    dec 25 = 10 padayen
    oct 31 = 8 padayen
    both evaluates to 25.

    you are not a real Engineer :P

    you explained very well BUT, you should always start from the last digit not the first digit.... so as you said base 8 is correct ...so you get 31 seprate 3 1 ..... and then start from 1....... 1x(8^0)[power] [as 8^0 = 1, 1x1 becomes 1] and then take 3 , 3x(8^1) = 24.......
    same goes for the base of ten :D:D
