6/2(1+2) in word a word problem
Have 6 apples, with 2 classes where combination of 2 boys & 1 girl.
So, each of them get how many apple(s)?
thus, 2 classes , 2 boys & 1 girl = 3 students + 3 Students = total 6 students
Now, only have 6 apples
6 apples for 6 students.
Therefore, 1 student only have 1 apple = 1
cool, let's leave logic outside and manipulate this into distributive property of multiplication that then implies a division so we can get the intended result.
nice try, but, again, you're only doing the same old 6/2(2+1) = 6/(2(2+1)) and being wrong.
Ok, I understand this is designed to piss people off, start arguments, and question mathematical notation, but seriously, anyone who grew up before you brought a graphing calculator to every math class should be saying 1. or even afterwards. If you want to say six halves multiplied by three, you just plain don't express it that way. "/" in a linear (typed, not actually linear) equation clearly deontes that everthing afterwards is the denominator of a fraction.
(Problem was we were forbidden to bring calculators both on classes and test etc. The one and only situation when we could have calcs was the abitur exam [I cant find any word in english to describe it so I use German] Fact is- I wasnt good at maths + Im using the methods we were given in primary/high school. Its almost 7 years after I left school and on studies I dont have to use maths at all. But I doubt I forgot how to make simple math tasks. I wont be giving here any links to www's proving Im right. What I was taught is 1) calculations in brackets- so in this case 2+1
2) both multiplication and division are equal [with their place in order] !but- you make them from left to right. So in this case 6/2 comes first, multiplication comes next. [so 6/2= 3 x 3 etc. = gives 9] and in case of method I have written above it'll be the same. )
