    288. Order of ops just states you add the 9 & 3 first, the 2 sits outside the brackets so the rest if done left to right because division & multiplication have the same point in the order hierachy.

    Pi does not = 22/7 it is only correct to the second decimal place. Use the scientific calculator here to verify http://www.ecalc.com/.

    Actually 22/7 is perfectly fine as many times during exams working to 2 decimal places was adequate for the example, this is before the days when you had Pi button on the calculator.

    I also break it down like this.
    48/2(9+3).
    48/2*(12).
    48/24=2.
    Only because I vaguely remember a teacher saying that brackets aren't open or "gone" until u apply ALL equations to it and since the 2 is basically part of that bracket equation that's how I did it. But I'm probably wrong.

    We used 22/7 in primary school anything after that it was unacceptable. Start pack for high school included the standard Casio Scientific calculator was awesome did like 90 digit equations that you could review.
    48/2(9+3) =
    48/2(12) = 288

    Having a value outside a brackets just means multiply which is equal to divided by in order of ops so you then progress left to right for it to equal 2 the equation would need to be this:
    48/(2(9+3))

    All this tells us is maths is fucked.
    I'm saying that cos alot of ppl ate getting different answers with people who work with numers getting both answers.
    Fucked I tell u! Lol

    No it just proves people are either dumb, have forgotten the basics since leaving school or they kind of remember it but are applying the rules wrong. They should also crack out their trusty Casio rather then relying on iphone apps which are potentially written by muppets with no idea as well and ignore things like BODMAS. You are only touching the values in between the brackets not outside unless it was 48 + 2(9+3) where by being a multiplication it would override the addition.

    It's kind of scary that we are actually debating basic year 7/8 Maths

    Yeah I saw it as the 2 being part of the brackets. Obviously wrong
    But I know the order of operations like I said just got the 2 part wrong.

    From some of my teachings, this chapter titled "2+2 = 4".

    In this section we deal with the philosophical context and presuppositions of mathematics.

    Needless to say, those philosophers who are not Christians would take issue with the interpretation of mathematics. But are the disagreements important? Can't a person do mathematics and come out with the right conclusion without any philosophy? Isn't the substance of mathematics philosophically and religiously neutral?

    Yes, non-Christians can do mathematics, but only because God enables them to do so. Only because the Christian God exists and sustains them and teaches them are they able to do mathematics, and to act as if God didn't exist.

    We can see this by considering the statement "2+2 = 4." Everyone agrees to this, right? Isn't this real and true knowledge, independent of a person's religious presuppositions? Not quite. A radical monist might dispute the truth of 2+2 = 4. Moreover, we have just made statements that depend weightily on a world view, on presuppositions about this world.

    2+2 = 4 is true. What is truth? What is the "everyone" that "agrees" to this truth? (What is man?)

    Furthermore, in order for someone to be a mathematician or even to write down or to think "2+2 = 4," he must have a confidence in his memory and in the reality of time. And there are more questions. What, after all, does "2+2 = 4" mean? A man with another language or another set of symbols would not understand it.

    Well, you may say, put two apples in an empty bag, add two more, and then count that there are four. At the very least, this involves someone remembering that he has already added the first two apples, and knowing how to count. It involves believing that time is not, e.g., circular. (Otherwise, adding the last two apples might be the very same event as adding the first two apples.) It also involves assumptions about the identifiability, stability, and constancy of apples in time. And so on. Furthermore, if we are involved in any kind of mathematical or even physical reasoning, we have to cope with an explanation or interpretation of logic.

    Now, all this may seem quite obvious. However, the point is that even the most elementary mathematical content involves an intrinsic commitment to a certain vaguely defined philosophy or world view. Every mathematician must have it to get off the ground. This vague world view assumes, among other things, that the world "makes sense" or that it "hangs together." Reality is not a complete flux, and man's mind is not a complete flux. What happens is not completely random and without sense. Man's mind, logic, and external reality cohere.

    Note that we have run across the word coherence before. We have seen that the Scriptures attribute the coherence of the world to the creative and sustaining activity of God, who has created man with a capacity for understanding the world, and who governs the world in an orderly way (for example, Ps. 104:20-23 speaks of the orderliness of day and night).

    Specifically, all things cohere in Christ (Col. 1:17). That is why it is possible to count, to remember, to communicate by language, to know truth. God bears witness to himself (Rom. 1:18) even in 2+2 = 4.

    We must say that mathematicians receive this witness, since they act on the basis of belief in coherence. They act as if 2+2 = 4 has real meaning, meaning that it can receive only as a truth related in manifold ways to the creation of God and to the other truths that he ordains. But this truth is suppressed, because it is denied that God is the Author of 2+2 = 4.

    Just remember a few numbers, it's not hard.

    I remember in school I went to the maths HOD in lunch break and said "3.141593" and was rewarded with a piece of pie.

    What makes it worse, is that it was in year 11 or 12, during which I had totally dropped match as a subject, and would have been on one of the very few days I actually attended school. But, free pie is free pie.

    Yea in later life I started to remember more of the decimal places but decided that I doesn't really matter that much anyway.

    run the logic it presents again using a circle with a diameter of 2, and therefore a square with sides that are 2 long...

    don't know that it calls for sterilisation, it was a bit of a headfuck at first

    big.

    fat.

    wrong.

    the 2 outside the bracket does not mean multiply - it is an "order"

    orders (the "o" in BODMAS) come before multiplication and division.

    (9+3) = 12

    2(12) = 24

    48/24 = 2

    therefore, answer = 2


    apologies - i'm wrong

    ^^^ Want to explain why the scientific calculator disagrees with you then. Orders are Squares/Square roots not a number outside/infront of a bracket which simply means multiply by.
