Both answers are correct, but only one of the formulas is
Authored by: Anonymous on Friday, March 01 2013 @ 03:30 PM EST

But both formulas are not correct for what one wants to do. Only one can be correct depending on the purpose you are applying the math. This means that one of your answers are wrong within any given useage.

If you think both can be correct within the exact same usage, I challange you to present a single situation in real world use where both answers are correct.

Additional math definitions are always required. For example:

    2+5*5
is the same as:
    2+(5*5)
but not the same as:
    (2+5)*5
(2+5)*5 is the correct formula for:
    You wish to sell one container with 2 oranges and a second container with 5 oranges at a price of 5 cents per orange.
2+5 = 7 oranges * 5 = 35 cents.

But if you use the other formula, you end up with 5*5 = 25 cents + 2 = 27 cents.

While your customer would love you selling 35 cents of oranges for 27 cents, it wouldn't be so good for your business.

Yes:

    Both answers are correct for each of 2 different formulas
but:
    only one formula is correct for a given application thereby making one of the answers wrong for that application.
I believe there was a Mars lander that crashed because someone used the wrong math and ended up using an answer that was wrong for the application.
