The solution to this is if the author of this problem write it in the correct notation (NO QUOTIENT MARK)

So it's either
48*[2(9+3)]^-1

or

48*(1/2)*(9+3)

which equals 2 and 288 respectively.


Also depends on the actual problem too, say I have nine friends and you have three friends that we need to feed, that's (9+3), and each of them eats 2 slices of pizzas per meal, that's 2*(9+3)=24 slices of pizzas per meal. Say you have 48 slices of pizzas, how many meal you can feed them, 48/24=2 meals of course.

They are doing 48 / 2(9+3) = 48 / 2(12) = 48 / 24 = 2.

That's the process many people are following.

Similar to the 3 guys and a hotel room riddle (does that sound weird?).


Three salesmen went into a hotel to rent a room. The manager stated that he had only one room left, but all three could use it for $30.00 for the night. The three salesmen gave him $10.00 each and went up to their room.

Later, the manager decided that he had charged the salesmen too much so he called the bellhop over, gave him five one-dollar bills, and said: 'Take this $5.00 up to the salesmen and tell them I had charged them too much for the room.' On the way up, the bellhop knew that he could not divide the five one-dollar bills equally so he puts two of the one-dollar bills in his pocket and returned one one-dollar bill to each of the salesmen.

This means that each salesman paid $9.00 for the room. The bellhop kept $2.00. Three times nine is 27 plus two is 29....... The Question: What happened to the extra dollar? Dun dun dun


The arithmetic is easy, the trick/twist is in the way it was asked.

excuse me... why are you adding brackets to the equation that weren't originally there? You can't just change the equation
