Order of Operations

Rule 1: First perform any calculations inside parentheses.
Rule 2: Next perform all multiplications and divisions, working from left to right.
Rule 3: Lastly, perform all additions and subtractions, working from left to right.

This is Grade 8 math folks....


Oh yeah, we are dealing with pilots who can't even handle adding decimals together correctly.

Think about it......

48
___________
2(9+3)

[gustind]

The above would be correct IF the initial expression were as follows:

48 ÷ (2(9+3)) = 2

48÷2(9+3) = 48 ÷ 2 x 12 = 48 x 12 = 288 = (48(12))/2

BEDMAS people

And this one little thread shows the arguement that

Association of Proffesional Pilots < College of Physicians

especially since pilots are supposed to be able to do simple math.

(hows that for stirring the pot)

P.S - Order of Operations is Grade 4 math - are you smarter than a 10 year old?

Explain how we're wrong? So it should be read as 48 / 2 * 11? I did 48 / (2 * 11) since division and multiplication could be done in any order, or at least that's how I was told in school. In strict computer language terms, wouldn't it be 288 all the time since it does the part in round brackets then read it left to right?

First of all, please don't tell me you just added 9 and 3 and got a sum of 11.



Second of all: http://en.wikipedia.org/wiki/Commutativity

You're saying that (x/y)*z = x/(y*z) holds true for any values of x, y and z, which is not true.

Yeah, we'll you're a socialist. But at least you like MacGyver, so that makes you a cool socialist.

Anyone who can not compete this simple problem was skipping school at far too young of an age.

Of course, you could also argue the fact that it's "been so long."

288. Now go sign your 'effin training bond.

p.s. I may have had an unfair advantage as I have a 5th grader in my house.

It's 2
48/2(x) where x= 9+3

[cdnpilot77]

It's 2
48/2(x) where x= 9+3

Right so it's: 48/2x(9+3) = 24 x (9+3) = 24x12 =288

Come on people, really?? This has to be a joke!!

[Nark]

2(9+3) is the lazy mathematician way of writing (2x9 +2x3). Then you divide 48 by that answer.

Thank goodness we have FMS's to calculate descents and crossing restrictions.

[wowo]

48 / 2 * (9 + 3)
= 48 / 2 * 12
= 24 * 12
= 288

I can't believe half the people who have voted think the answer is 2.

[Nark]

The equation isn't 48/2 x (9+3)

The equation is 48/ 2(9+3)

[cdnpilot77]

The equation isn't 48/2 x (9+3)

The equation is 48/ 2(9+3)

Its the same thing...if it were written 48/ (2(9+3)) then you would be correct

[cdnpilot77]

you guys have me second guessing myself here now on grade 5 math. Can a math major please solve this problem...lol
