You have one apple. You divide it into quarters, so that you have 0.25 of an apple. Now divide it in half. So yes well technically you do have one half of 0.25 (and 0.5 is the answer that a calculator will return) what you actually have is 1/8 of an apple (0.125).
This is what pisses me off about Matt half the time. You end up with something that in the abstract makes sense because it's just numbers, but then if you try to make it make sense in real life it's stupid.
Your confusion comes from the fact that dividing a quarter in half is 0.25/2. That's not what's shown in the comic. Dividing by 0.5 is the same as multiplying by 2. It's just a quirk of syntax, the way we write math. If you spelled it out using English the comic would say "multiplying a quarter by two equals a half". The confusion just stems from someone's unfamiliarity with mathematical notation.
exactly. failure of english, not math. Math allows fairly accurate descriptions of the universe, humans (and especially languages) evolved to adequately percieve the narrow band of qualia that have been relevant to survival
