Many people will get 2.

Subtraction is the same as adding the additive inverse (the opposite) and division is the same thing as multiplying by the multiplicative inverse (the reciprocal).

Therefore, 48/2(9+3) is 48*.5*(9+3) which is 24*12 = 288. (.5 is the reciprocal of 2)

When using the PEMDAS convention, M and D are done simultaneously left to right because multiplication is commutative and since D is really M by the reciprocal. When using the PEMDAS convention, A and S are done simultaneously left to right because addition is commutative and since S is really A of the opposite.

Every expression can be re-written to not use division and to not use subtraction. You'll have multiplication by the reciprocal and adding the opposite. When doing that, PEMDAS simplifies to PEMA.

You math geek! 😛

So maybe, as above so below? Or maybe we can exclude below or above? I'm sure you're one of the few people who could get these questions.

That is amazing. In school, you are taught to first work the right side of the problem (9+3). Then move left..so it looks like this:

(9+3) is 12...

2(12)

24

48/24

2

But he actually starts with 2 being the critical link between both equations.

48/2 (or 48*.5)

24

then he goes to the right side..

(9+3)

12

bringing it home...

24 x 12 = 288.

It is the exact same equation with 2 outcomes depending on one's interpretation of it. That is a great metaphor in life. Also, if you aren't open to other interpretations, you just won't see it.

AWESOME video, at1... :thumbup:

Dawkins thinks belief in God is an excuse to evade thinking in the scientific world. Sadly, he is ignorant to the list of christian scientists who have contributed & founded many of the sciences he himself believes in. How ironic.

LOL..yup!

Apparently, this discussion (whether it "is" 2 or 288 or something else) rages on in the interwebs. A ring theorist studies generalizations of the integers (which form the prototypical example of a ring) all day long but that in itself doesn't make him an authority on integers because arithmetic is pretty far removed from what they do in day-to-day work. They think about pretty strange, abstract stuff far removed from actual numbers.
