DeBingJos Minmatar Goat Holdings	Posted - 2011.07.19 07:59:00 - [61] Originally by: Trig Onami I understand your reasoning, but Ommision implies grouping. Grouping stays intact in all equations. You can't "ungroup" the 2b once it's formed. 2(b) is not grouped, that is the error you make. 2 * (b) is not the same as (2 * b) 2 * (b) is the same as 2 * b For your information; if you google this problem you will get quite a lot of results. google math result

Kieron VonDeux	Posted - 2011.07.19 08:02:00 - [63] Originally by: Trig Onami I don't know but I can't stress enough the fact that 288 only comes when people don't use algebra to solve it. That is because you don't know what you are doing. You didn't do your multiplication left to right. You should have solved for 48 / 2 * b not 48 / 2b Do what is in para first, then multiplication and Division left to right. =48 / 2(3+9) =48 / 2 * 12 =24 * 12 =288

Jacque Cruix	Posted - 2011.07.19 08:30:00 - [66] Originally by: malcovas Henderson The thing to remember here is the "/". This is means "over" implying it is in fact a fraction read thus 48 over 2(9+3) or 48 ---- 2(9+3) Not once do you see the division sign in the the equation. You only assume "/" = division. It is not the case. The answer is 2 That is incorrect. What you suggest would be written as 48 / (2(9+3)) Your assumption was the cause of grief for many in my last math class not too long ago.

I re read the question and I am wrong. It is not 48/2(9+3). The division sign is in fact there. not the "over" sign
Kitty Meow	Posted - 2011.07.19 08:38:00 - [69] Edited by: Kitty Meow on 19/07/2011 08:40:21 Ok, so its a troll topic, but still, Look at it in this manner :- 48/2(9+3)= 48/(18+6)= 48/24= 2 It's inside brackets first then next to brackets, or as in the above solution, work out the bracket anyway :- 48/2(9+3)= 48/2(12)= 48/24= 2
Trig Onami Caldari Onami Corporation	Posted - 2011.07.19 08:43:00 - [70] Did you know: You can guess the very close approximate ( +/- .00000002 ) decimal value for all fractions of the number 49 by multiplying them by 1, 2, 4, and 8 as follows: 1/49 = .01020408 (or double every 2 digits) 2/49 = .02040816 3/49 = .03061224 4/49 = .04081632 5/49 = .05102040 6/49 = .06122448 7/49 = .07142856 8/49 = .08163264 and so on.... Figured this out when I was 10 years old. The answer is still 2, by the way. EVE. The most ambitious project on earth.

Makko Gray Nexus Aerospace Corporation	Posted - 2011.07.19 09:03:00 - [72] Edited by: Makko Gray on 19/07/2011 09:03:49 The answer is to write the equation more clearly to avoid ambiguity. For example... 48 / 2 * (9 + 3) (48 / 2) * (9 + 3) (48 / 2)(9 + 3) ...would all be alternative ways of expressing the same equation with the bottom 2 being clearest.
Trig Onami Caldari Onami Corporation	Posted - 2011.07.19 09:12:00 - [73] Originally by: Kieron VonDeux Originally by: Kitty Meow Edited by: Kitty Meow on 19/07/2011 08:40:21 Ok, so its a troll topic, but still, Look at it in this manner :- 48/2(9+3)= 48/(18+6)= 48/24= 2 It's inside brackets first then next to brackets, or as in the above solution, work out the bracket anyway :- 48/2(9+3)= 48/2(12)= 48/24= 2 You have violated the "order of operations". Nope. 2(12) = (Group2((Group3)) because the '2' is TOUCHING the '(12)' bracket. When '2' is touching the bracket '(' it explicitely bonds with the contents of that bracket. It cannot be separated like you are doing. That's why this becomes an algebra equation. When b = 12, then 2(b) = 2b = 24 Order of Operations does not APPLY until after this particular group is solved. The ONLY way this equation can be answered with 288 is if it was SPECIFICALLY Written like these 3 examples: 48 ˜ 2 x (3+9) (48 ˜ 2)(3+9) (48 ˜ 2) x (3+9) EVE. The most ambitious project on earth.

TedStriker The Scope	Posted - 2011.07.19 11:26:00 - [81] Somewhere on this planet **ed up teachers or schools must teach ppl to just "make up brackets" as they go along 2(1+2) IS NOT** (2(1+2)) 2(1+2) IS 2(1+2) Not the bracket is omitted, the multiplication is. There is no "grouping" rule going on here that would have ANY validity outside of some ***ed up science-paper writing scheme that some scientists use because in their little world they write it like that (leading to alot of confusion btw, they should just be shot right now).

Morbidusk Yotosala	Posted - 2011.07.19 13:35:00 - [86] It's really not that hard if you dont think too much into it. The OP whether tolling or whatever got enough folks with this. 48 / 2(3+9) = ? Simple 48 / 2(12) = ? 48 / 24 = 2 Why? No matter the division of 48 or the multiplication of 2 * 12. The fact is that 12 remains in "( )" unresolved. So you handle that multiplication first. The result is divided into 48 giving you the correct answer of 2. As far as if someone uses either of the division symbols does not matter.

Taedrin Gallente Zero Percent Tax Haven	Posted - 2011.07.19 14:02:00 - [89] In my 25 years of life, I have NEVER heard that "omission implies grouping". Omission merely means multiplication. Think about it this way: 2x^3 + 5x^2 - 3x + 1 If "omission implies grouping" this would be mathmatically equivalent to: (2x)^3 + (5x)^2 - (3x) + 1 Which is false. Because the omission of an operator implies multiplication and exponentiation has a higher precedence than multiplication, we have 2x^3 = 2(x^3) and 5x^2 = 5(x^2). so 2x^3 + 5x^2 - 3x + 1 = 2(x^3) + 5(x^2) - 3x + 1 ---------- Originally by: Dr Fighter "how do you know when youve had a repro accident" Theres modules missing and morphite in your mineral pile.
