>If John has 3 apples, and Elizabeth has 4 oranges, how much fruit do they both have in total?
when I was little, I thought the answer was 7. but now that I'm a math major I realize that you can't add up apples with oranges because they are different things and the things you add together must have the same unities. I also know that I can't use the numbers 3 and 4 so freely because I don't really get set theory, I failed it last semester, and without it the numbers 3 and 4 are ill defined. Also there's the question on whether 7 is the only answer possible, which makes it necessary to prove some sort of unicity theorem.
So if you ask me the same question now, I would reply "I don't know"

This division by zero hurts me

apples and oranges are subsets of fruit. Shit b8, try harder next time.

well, then apples and chairs

Then he has 3 fruits. Math is about rigor, not psuedo-intellectual posturing.

From line four onwards there's an implicit 0 on either side of the equation that you're ignoring.

Retard. The set of fruits is a union of apples and oranges, So the total number of fruits is:
[math] n(F) \geq 7 [/math]
Inequality because the question doesn't specify if that's exactly all the fruits the two have.

pears aren’t fruits anymore?

There is nothing stopping you from adding 3 oranges and 4 apples to each other and then dividing that by 5.5 bananas. In math, that is.
In physics it is illegal because in physics we have units, and those units have physical meaning, and that meaning is derived from a rational exploration of reality, as diametrically opposed to the irrational masturbation of imaginary sets and operators.

I address that later, I should have said atleast earlier though. So, my bad

He's mad because you're retarded, and dealing with retards is frustrating.

I introduce the physical units of apples and oranges. I can make physical observations with those, eg there are 3 kiloappes in a food truck. By the very rules of dimensional analysis, I can’t add them.
