I Need Help Solving This Math Problem

[The Duke]

I totally agree and I can sort of see where 11 is coming from now because I'm currently talking to another math whiz.

Does he know his gazintas and naughts?

God bless you.

I used to use that daily.

I've made crude altimeters using it....They were pretty accurate.

It works.

Okay so I still say that the answer is 5 after looking at it more clearly because if we're doing:

3x3÷3-3+3


From left to right the addition comes first before the subtraction.

Order of Operations.

Exactly and going from left to right we have to skip subtraction because it doesn't come before addition.

11

We call it BEDMAS in Canada Brackets, Exponents, Division/Multiplication, Add/Subtract.

In Texas public schools, it is now GEMDAS, with the ‘G’ standing for ‘grouping symbols.’

Addition and subtraction really dont matter. Its in the article.

Multiply. Division comes first. UNLESS YOU HAVE ()

I THINK that the answer is: (I did this with a calculator btw for the record.)



638,1,192


I'm not sure if the commas are in the correct place though.

I do believe that we're supposed to use PEMDAS here but I'm not sure how to get the final answer. It's:

3x3-3÷3+3


Now according to PEMDAS you would multiply 3x3 and get nine and three divided by three is one, three plus three equals six and finally three minus three is zero but is that what we're even supposed to do here because I don't know how to get the final answer.

From left to right the addition comes first before the subtraction.

Now you changed the original problem.
Addition Doesn't come before Subtraction, they are EQUAL, you do whichever one (Addition or Subtraction) come first.

No you were right the first time. It's 3.




You ALWAYS do as that part doesn't change.

No you goof… it’s 10!! ;-)

 

[Slade3200]

Now THAT's 3!

Oops, or 8.

Or 10 ;-)

 

[Slade3200]

2x4-6÷2+5
2x4=8-6=2divided by2=1+5=6 the answer is 6

You gotta do the multiplication and division before you do the addition and subtraction

Okay I'm back to seeing 11 again. This is just whack.

I get 6,211,028.8

Well I'm not sure if I did the exponents right.

It's sort of funny how I started this topic a couple days ago and I still got two people in real life screaming in my ear as one is saying it's five and the other 11.
