What is 6÷2(1+2) = ? The Correct Answer Explained

Wow, me too? You just ignore anyone who refutes your "philosophy"? Pathetic. Why are you even here if you just want to talk to yourself?

 

I got 15 for that McDonald's Maths Quiz

 

NO! Multiplication and division have equal rights. You do them from left to right.
5*6/3 = 30/3 = 3
10/2*3 = 5*3 =15 left to fight
NOT 10/2*3 = 10/6 NOT multiply first.

 

Way too easy 17

 

I got 5 + 1 x 10. For McDonald's

 

Parentheses
We see parentheses all the time when we read. They are the round brackets that separate a group of words from the rest of a sentence in our English language. They usually contain a phrase (like this) that helps us understand the sentence more. In math, parentheses also help us understand our problem better. But we use them in a slightly different manner. We use parentheses in two different ways, which we will talk about in this video lesson.

Multiplication
The first way tells us to multiply. When we see two or more numbers together that are separated by parentheses, then the parentheses are telling us to multiply. For example, when we see 5(2), the parentheses are telling us to multiply the 5 and the 2 together. We can write 5*2 like 5(2) or (5)2 or (5)(2). All of these are multiplication problems, and they all equal 10.

If we see 4(3)(2), it means to multiply the 4 with the 3 and the 2. We get 24. When we are working with parentheses, we can leave the first or the last number without or outside the parentheses. It still means multiplication. Use your imagination and imagine that the parentheses are two arms giving a hug. You can think of the parentheses as telling you to hug or multiply the love between the numbers.

Order of Operations
The second way in which parentheses help us out in math is in telling us which numbers to work with first. In the order of operations, parentheses comes first. If you see parentheses with more than one number inside, you immediately work with those numbers first. It's like a pair of arms holding onto a group of precious items that you don't want to forget. You see them and you put them away first.

first do within the parens:

(1+2) = 3

then multiply:

2(3) = 6

then divide:

6 '/. 6 = 1

Q.E.D.

 

Yeah, this was school.


And this was after school activities.


And this was me in Year 11.


And this is why I liked going to college.

No race wars in college.
No police, no fights, no one getting pregnant or closet gay or teacher stalking or nothing in college; the other stuff like needy attention seeking and drugs.

 

That's some serious hair !!

 

6÷2(1+2)

Have you not read the posts? Multiplication and division have equal rights.
6÷2(1+2)

(1+2) = 3 so far, so good
That gives 6÷2(3)
Since all that is left is Multiplication and division, we go left to right
6÷2 = 3
That leaves 3(3) or 3*3
9

In an earlier post, to some who knows as little about math as yiostheoy, I said "You can lead a horse..."
I guess there are some horses you can't even lead to water.
yiostheoy, in case you didn't put me on ignore, go to Google and enter 6÷2(1+2). Go ahead, try it.

 

I'll try. 6/2 =3*(1+2) =
3*3 =
9
AFAIK, it's left to right when = math signs in an equation.

alternative:
6/2*3 = 9
So officially, I go with alternative.

 

It is amazing how many people here had crappy 7th Grade math teachers.

 

My 7th Grade math teacher was an old tall Catholic nun named Lena Japp.

She was a great teacher.

She was ugly as sin in the face but otherwise a beautiful soul.

 

Parenthesis 1st. 6/2 had no parenthesis in the original equation. So a rewite is 6/2*3.

 

3*3 = 3^2 = 9

 

Yes indeed, certain bad at math philosophical types don't understand that subtraction is the same thing as the addition of the negative, and division is the same thing as multiplying by the reciprocal. Remind me to never take a philosophy class. Apparently it dulls the brain as it expands the ego.

 

I used to love algebra. I actually tutored in algebra and got paid too. I have never been great at math though, unfortunately. Algebra was different for me though. Like a game with numbers. I actually enjoyed doing my algebra homework. I know, kind of nerdy, right?

 

Your equation rewrites a 7+1+49-7
= 50

 

left to right when all signs equal

 

If there are no definitions, then chaos is the result

 

7th Grade obviously did not work for a lot of people.

 

Just like pulling oxygen flow on humans. It will die and not even be a hunk of metal.

 

Page 4 proves philosophy is pure opinion.

 

Philosophy is pure human thought applied to a-priori truths to arrive at a-posteriori deductions.
