Somedude Posted July 31, 2019 Report Posted July 31, 2019 1 hour ago, reality said: So, how do you write an equation for something divided by something times something? For example, I came up with this word problem: There is a total of 8 gallons of gas available. 4 bikers need to use that equally to travel from point A to B and back to point A, by spending all of it. How many gallons each biker would spend to travel one-way? 4 biker 2 way——> 8 gallon 1 biker 1 way——> 1x1x8/4x2 = 1 But, unfortunately, calculators are not designed/configured to decode intricate equations. They just give you results for straight forward (assumptions) equations, which need not always be treated as truth. Ilanti questions ke 'order of' in BoDMAS pettaru man to avoid the confusion. 'of' (another form of multiplication) has precendence over division ...it helps forcing the people come up fomralized version of problems. If people don't agree for standards for these kind of informal questions, solution would be always ambiguous and would be many. BODMAS is vastly agreed by number of Mathematicians. Quote

In your problem you want to know how many gallons per each bikeway... one bike way means one way for every bike... so its gallons/(bikes* number of ways)... 8/(4*2) = 1 Why extra pair of brackets for denominator only. Why not for Numerator? Which rule book tells to do that? Looks like people are just making up formulas (adding brackets) to just satisfy what google/most of calculators are returning. Quote

It stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. PEMDAS is often expanded to the mnemonic "Please Excuse My Dear Aunt Sally".[5] Canada and New Zealand use BEDMAS, standing for Brackets, Exponents, Division/Multiplication, Addition/Subtraction. Most common in the UK, India, Bangladesh and Australia[11] and some other English-speaking countries are BODMAS meaning Brackets, Order, Division/Multiplication, Addition/Subtraction. Nigeria and some other West African countries also use BODMAS. Similarly in the UK, BIDMAS is used, standing for Brackets, Indices, Division/Multiplication, Addition/Subtraction. 1 Quote

(8/4)/2... which is gallons per bikes per ways..... what I said was gallons per bike ways.... So you either write it as 1) Your way... (Gallons/Bikes)/Ways = (8/4)/2 = 1 this is Gallons per bikes per way 2) My way ... Gallons/(Bikes *Ways) = 8/(4*2) = 1 this is gallons per bike ways Only thing is you got your equation wrong to get a wrong answer And, NO, I didnt find anything above in google, just what I remember from my head.

chittimallu_14 Posted July 31, 2019 Report Posted July 31, 2019 Writing a plain equation like the above ones by TS are different from the example of a real life which @reality gave... One can just blindly write 8/4x2 and ask what the answer is. However if you put that in real life issues with words like bikes, gallons and ways then the equation needs to be re written based on the actual problem with brackets, you can use brackets in either numerator or denominator like reality demanded but the usage of D or M or something else might change... Based on your example here you either write it as (8/4)/2 or 8/(4*2). I guess that is my understanding atleast Anyways im out of here, it was fun discussing these with you all. Quote

It was a general question... extra bracket requirement denom ke endhuku, why is it not needed for Num ani? yes you can use bracket in numerator but then you need to write the division and multiplication accordingly based on the problem... think for a while you will understand the difference... Basically you are interpreting the equation wrong by using brackets for the numerator and then multiplying (instead of dividing) by the next number. Use my acceleration analogy for better understandin, if acceleration equation is written like the way you interpreted... it will become (distance/time)*time which is wrong so it should be 1) your way with brackets on numerator... (distance/time)/time 2) my way with brackets on denominator .... distance/(time*time) Use brackets either upstairs or downstairs but change the multiplication or division accordingly for the case Quote
