You have a problem.

A problem? As in one?

 

[CANDawg]

Its 9.

BEDMAS to the rescue.

 

[Anjel]

Its 9.

I was in between the two lol

I forgot you can divide first if it comes first in the equation.

Anything not in ( ) is left to right.

6/2=3(3)=9

6/2=3(3)=9

What about PEMDAS!!!?

So

4+4-5(3+4)*6

() then * then + then -

 

[JPINFV]

Multiplication/division and addition/subtraction have the same priority in their respective groups.

Edit:
=6/2(2+1)
=6/2(3)
=3(3)
=9.

It's been a while but I think multiplication and division don't supersede one another by order in equation? I forget. Been years.

They don't. If you have multiplication and division in the same problem then you work left to right.

6/2(2+1)=X
Is the answer to this 1?

x=1

Now, to be a smarty.... It depends on how you read it.

Option 1: 6 over 2(2+1)
You would add the (2+1) which equals 3.
You then have 2(3) which means multiply 2x3 which equals 6, which leaves you with 6 over 6, or 6 divided by 6, which of course equals 1.

Option 2: 6 ÷ 2(2+1)
You would add the (2+1) which equals 3.
You could then read it as 6 divided by 2 times 3.
So 6 ÷ 2 = 3, then 3 x 3 which equals 9.

They don't. If you have multiplication and division in the same problem then you work left to right.

But multiplication and division both come before addition and subtraction.

I know. That's why I only said it about multiplication and division. I was too lazy to put the + and - come after it but in the same working order of left to right.

 

[Achilles]

The answer is 9
6 divided by 2 is the same as 6 over 2, they both reduce to 3.

Excuse me while I go have some Pi which equals 3.14159

If people would just learn to use ÷ instead of / then....

a^2+b^2=x^2

3^2=9
4^2=16
9+16=25
x^2=25
x=5

 

[Achilles]

a^2+b^2=x^2

3^2=9

9+16=25
x^2=25
x=5

wow duh!
had 28 for c^2. :sad:

Yes, but if there is both multiplication and division you work left to right, following exponents, or rather in this problem, parenthetical problems.
I like how like a freshman algebra level problem has cause like 3 pages of people trying to work it out XD

ban buses they kill large numbers of people.

Where did c come from in that equation jpinfv posted?

a^2+b^2=x^2
