6÷2(1+2)
THREE WAYS to solve this question:
1st WAY:
just forget about the PEMDAS or BODMAS rules,
lets come back to the origin of mathematics which is solving human's problem:
assumption: 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 gals = 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 (answer)
2nd Way:
6÷2(1+2)
lets assume y =2 so that , 6÷y(1+y) = 6 ÷ (y+y^2)
now replace 2 into y it shows 6 ÷ ( 2 + 2^2) = 6 ÷ (2 + 4)
= 6 ÷ 6
= 1 (answer)
3rd way:
6÷2(1+2)
lets assume (1+2) = a so that, 6÷2a
now = 6/(2a) 2a is slightly different with 2 x a ; please dun tell me that is (6/2)x a !!
lets simplify = 3/a
now replace (1+2) into a = 3 (1+3)
= 3/3 = 1 (answer) if you not agree again! fine lets go for the 4th way
4rth Way
6÷2(1+2) from this equation , we would say it has two group , A = 6 ; B = 2(1+2)
lets 6÷2(1+2) = z so that, A/B = z
A = zB
6 = z[2(1+ 2)]
6 = 6z
z = 6/6 = 1 (answer)
come on, don't be stubborn any more.
i am going to END this Equation now.

Hahaha. Nice.

6÷2(1+2) With pemdas,you work left to right after parentheses 6÷2x3 LEFT TO RIGHT 3x3 9
-
No you must follow order of operations so you would multiply before dividing
-
No,that's just the way they put PEMDAS You go left to right
-
No, multiplication and division are solved left to right.

Implied multiplication into parenthesis comes [b][i][u]FIRST[/u][/i][/b] Familiar with functions like these; A(1x2) x b(2x3)= a(-1x-2) x b(-2x-3) ???

It has a solution that type of function is called a quadratic algebraic equation an deals with coordinates on a graph

I know,I just did want I usually do when I see a problem like this. That being said,our little problem has a solution,this doesn't,so why us this a good example? [spoiler]I'm not kidding,unless I'm missing your point[/spoiler]
-
Implied multiplication n(a+b) Is done first as its considered part of the parenthesis Doing it 2nd changes the solution entirely. Implied multiplication is extensively used in graphing and matrix equations and very essential to computing and 3Dimensional calculations
-
Let's agree on this Pemdas=9 Any other way equals 1 Agree?
-
Pemdas Parenthesis first Implied multiplication is part of parenthesis Using pemdas answer is 1
-
Using pemdas is 9 Multiplication does not come before division You go left to right
-
If there is a number nxt to the parenthesis you multiply that into the parentheses [b][i][u]FIRST[/u][/i][/b] cuz its part of the parenthesis
-
No it's not.
