phart Posted November 14, 2020 Share Posted November 14, 2020 This is trending on twitter. Considering many moons ago we argued on here for what seemed like months dividing by zero, what answer do folk get. In honour of FE coming back temporarily as one of the original participants of the /0 "debates" Not sure when BODMAS became BIDMAS mind you.

Lamia Posted November 14, 2020 Share Posted November 14, 2020 I only remember the 11m2 debate and the Eagle/Buzzard one! 😆 Quote Link to comment Share on other sites More sharing options...
phart Posted November 14, 2020 Author Share Posted November 14, 2020 I can't remember the 11m2 one. They all seem hilariously pointless now. I'm glad I didn't have to argue with me back then lol! Quote Link to comment Share on other sites More sharing options...

Flat Earth Posted November 14, 2020 Share Posted November 14, 2020 At the risk of getting involved in a pointless argument I get the answer to be 1. The eleven square miles thing was an argument about an area of the Amazon jungle where a real live baby t-rex had been seen. I can't really remember the gist of the discussion, only that our favourite conspiracy theorist was arguing blind with me that an area 11 miles long and 11 miles wide was 11 square miles. Quite why we were arguing about the area of jungle rather than the veracity of the baby t-rex claims, I can't remember. Quote Link to comment Share on other sites More sharing options...
Flat Earth Posted November 14, 2020 Share Posted November 14, 2020 And philosophically referencing calculus, with the numerator equal to one, as the denominator trends towards zero the answer trends towards infinity. 1/0.1 = 10. 1/0.01 = 100. 1/0.001= 1000 etc. Only a pedant would disagree that 1/0 wasn't equal to the mathematical concept of "infinity".

Orraloon Posted November 14, 2020 Share Posted November 14, 2020 I'm going for 1 as well, but it's probably a trick question? The Buzzard thread was a cracker. I remember the dinosaur in a cage but can't remember anything about the 11 square miles bit. Quote Link to comment Share on other sites More sharing options...
Flat Earth Posted November 14, 2020 Share Posted November 14, 2020 Oh aye, and its not "math", its "maths". FFS how do you cope with the screen jumping all over the place every time the board throws a new advert at you? Quote Link to comment Share on other sites More sharing options...

When I did maths the order would be : brackets first, then multiplication takes precedence over division. If they wanted us to do the division before the multiplication then the 6/2 bit should be in brackets (6/2). Conventions may have changed though. It was long time ago.

BIDMAS - Brackets, Indesis, Division, Multiply, Addition, Subtract Brackets - 2+1 = 3 No indesis Division - 6/2 = 3 Multiply - 3x3 = 9 No addition No subtract So answer still is 9? That might be a crazy way to work it out. I used to help my daughter out and was often wrong. Not really my subject. Quote Link to comment Share on other sites More sharing options...
Orraloon Posted November 14, 2020 Share Posted November 14, 2020 Mixed division and multiplication[edit] Similarly, there can be ambiguity in the use of the slash symbol / in expressions such as 1/2x.[12] If one rewrites this expression as 1 ÷ 2x and then interprets the division symbol as indicating multiplication by the reciprocal, this becomes: 1 ÷ 2 × x = 1 × 1/2 × x = 1/2 × x. With this interpretation 1 ÷ 2x is equal to (1 ÷ 2)x.[1][8] However, in some of the academic literature, multiplication denoted by juxtaposition (also known as implied multiplication) is interpreted as having higher precedence than division, so that 1 ÷ 2x equals 1 ÷ (2x), not (1 ÷ 2)x. For example, the manuscript submission instructions for the Physical Review journals state that multiplication is of higher precedence than division with a slash,[22] and this is also the convention observed in prominent physics textbooks such as the Course of Theoretical Physics by Landau and Lifshitz and the Feynman Lectures on Physics.[d] Quote Link to comment Share on other sites More sharing options...
phart Posted November 14, 2020 Author Share Posted November 14, 2020 It's written badly deliberately to start arguments I think. Hence why i brought it into discussion. Quote Link to comment Share on other sites More sharing options...
