Oh I'm not trolling... Just trying to figure out how you guys are separating it out. Using that logic, that means 6
From a previous wiki reference - Similarly, care must be exercised when using the slash ('/') symbol. The string of characters "1/2x" is interpreted by the above conventions as (1/2)x. The contrary interpretation should be written explicitly as 1/(2x). Substitute (1+2) for x and it's case closed. The division sign was covered by the mathematician. You were taught that 3x is the same as 3*x, focus on that.
That one I can follow. 6/2(x+y) being equal to 3(x+y) I have trouble following. substituting (1+2) for x in that example is still not the same, as you only have the multiplier. So you can follow my logic, I was taught 6/2(x+y) is 6 --- 2(x+y) which is same as 6 --- 2x +2y Sounds like something to send to school with my son, and see what answer his algebra IV professor sends back EDIT: never mind - I see your reference . almost 5am here. 1/2x = 1/2(x), 6/2x = 6/2(x). Still curious as to what his prof will say
That's the part that's incorrect. 6/2(x+y) is 6 --- (x+y) 2 See the difference? You can't put just the 2 in the parenthesis, the way you're doing it, you're supposed to multiply the entire "six halves" against x and y. The 6/2 part doesnt need a parenthesis to go before the 2 * (3) part since it's equal in order of operations and leftmost.
Order of operations - Wikipedia, the free encyclopedia Scroll down to "Gaps in the Standard." What this section states (or implies) is that if you try to interpret 6
Oh, don't worry guys - it was a MAJOR facepalm moment when the light turned on His example, fyi, if you were to ask me what 1/2(1+2) was, I could literally read it out as "one half times one plus two". so, 6/2, 1/2, makes no difference. Call it "six halves times one plus two" and the result is 9. Guess that's why it's a math problem. I assume it's the 6/2 throwing folks off, I dunno. I think if you were to ask what 1/2(1+2), most people would probably get it right And to answer n0ct3m, yes, it's settled, and the answer is 9. And, sadly, the Atrix bootloader is still locked Oh, and I'd like to apologize to my teachers, because there is NO WAY they taught me that 6/2(1+2) = 1
I maintain that this thread is full of nerds. I don't think that puts me in a very good position now....
9 I did that shit in my head.... The answer to the problem depends on how it's written and in this case... 6/2(1+2) 6 / 2 * 3 3*3 9 You always do math left to right, like reading a book, or this post. Always solve for whats in parentheses first. Then solve ops like square roots & powers. Then solve muliplication & division, left to right. Then addition & subtraction, left to right. It's not phrased "6 / 2 + (1 + 2)" so how you get anything but "9" is beyond me.
