See, the last panel is just how it worked out in my last relationship, if one of us made a big irrational purchase, the other had full right to do the same...

this is why I stopped making big irrational purchases...

you're not dividing by zero. its very simple 0/3 = 0% 1/4 = 25% difference between 25% and 0% (25%-0%) is 25% WOAH. A 25% INCREASE... would you look at that!!

Actually, as stated before, if you go from playing 0 out of 3 consoles, to playing 1 out of 4, it's an infinite percentage increase. Not the difference between 0% and 25%. 25% really only says the percentage of consoles you own that your playing, not the percentage you increased.

Not that I'm nit-picking the comic, just the commenters. The comic, much like the rest of the comics, is hilarious.

You're all wrong. It's a comic. Does it really matter whether or not the percentage was correct? Just enjoy the silliness of it and leave the math to people who obviously have way too much time on their hands.

Seriously, did none of you lot graduate middle school, or are you just trolls?

Let " % difference" be defined as " (new value - old value) / original value." (this is a basic formula from any 6th grade or higher math or science textbook.) Let "original value" equal 0, as it does in the comic. ( Because that's the number of consoles which he originally plays.)

Then it doesn't matter what "new value" is (it's 1, by the way) because you can't divide by zero (2 would be algebraically equivalent to 3 if you could. this is one of innumerable examples--algebra would literally cease to function if you could divide by zero.) This is why the term for the value of a number divided by zero is "undefined" which is math-talk for "a meaningless or impossible-to-determine value." It is not an infinite percent increase. It is not a 25% increase. It is not a 33% increase. It is undefined.

Irmansul is the closest to being correct. It won't just give you an error, you actually made an error by attempting the operation in the first place.

And I didn't need my damned degrees in Engineering or Physics to know that. A GED would have sufficed.

Even if it's a long time ago, I'll call you (nearly) all ignorant. It's an infinite increase (infinite percent), but a 25 percentage point increase from 0% to 25%).

Actually, everyone is kinda wrong. You can either measure the difference between 2 percents in either a third percent(%), by dividing the second percent by the first, or you can measure the difference in percentage points(pp), by taking the first away from the second. Therefore, the change in consoles played is (/0)%, or 25pp, and consoles owned is 20%, and is not measurable in pp because you need 2 percents to measure it. If you don't believe me, look up percentage points and percent on Wikipedia.

...and when you're looking all serious and stuff, you look like Henry Rollins with his head shaved and smaller arms.

Isn't it a 33% increase, actually?

It's actually an infinite increase. You start with 0 and go to 1. Zero can get multiplied infinite times.

Just sayin'

no....neck is toooooo small.

You two are both idiots. It is a 25% increase. 0 of 3 is 0%. 1 of 4 is 25%. Are you 8 years old?

You can't divide by 0, so it's an /ERROR/ % increase n_n

you're not dividing by zero. its very simple

0/3 = 0%

1/4 = 25%

difference between 25% and 0% (25%-0%) is 25%

WOAH. A 25% INCREASE... would you look at that!!

0/3 is not dividing by zero.

3/0 is.

Did she buy a Santa Claus beard?

Or just say, "I did something stupid. In return, you get an extravagant purchase of your own!"

In other words, skip all the other stuff :D

Rollins? Let's try Kane from Command & Conquer.

Some people are just incredibly bad at math.

And here I was thinking that it was a 100% increase, because he used to not play console (0%) and now he plays console (100%)

33.3333... % would be the increase in your console ownership, and 25% increase would be the amount of times your playing of said consoles increases.

Thank you so much, jmpc.
