okay i'll stop messing around, my point is some shouldn't criticize other people, they can be dead wrong when they think they're right.

i think you could post this on ANY THREAD ON THIS FORUM...

try all of the "should i eat my exercise calories" threads.

try all of the "should i eat my exercise calories" threads.

Where is that thread? I've been wondering about that very question and haven't seen it discussed any where!!!!!!

OK I think strange. I got seven and for the right reasons, but work is odd.

9-5+5*0+3 = 4+5*0+3 = 4+3 = 7

There's nothing really wrong with doing it that way as long as you understand that + and - separate the various terms, and that each term is calculated independently. Which you clearly do.

I got 7.

PEMDAS is correct, but I know also that MD and AS are grouped together and when you have both MD or AS, you just work left to right. A lot of people are taking PEMDAS as literal, forgetting that it's multiplication AND division, addition AND subtraction.

Left to right, people! It's 7!

7 , order of operations means you do 5 x 0 first, then add/subtract

Okay I started right remembering the German saying: Punktrechnung geht vor Strichrechnung and remembering that somthing times zero is zero so I got
9-5+0+3
and then I worked backwards :S
I don't know why, I know it is not 1 but 7 but I have to admit I am a totally confused demon that calculates backwards

But then I am glad I can still figure out what to pay whendoing grocery shopping without using a calculator
I even can somtimes find out what 10 percent of something is just using my brain

And I was never really good in maths

So I admit I got it wrong, I found my mistake and I try to keep it in mind

But "maths" should be "math."

Thanks for asking!

If you're in the UK it's maths. Math(ematic)s.
You wouldn't say Matematic. Or would you? I dunno, but anyway, yeah Maths is correct in most places.

I've read enough Harry Potter to know y'all call it "maths" over there. I was just joshing.

I don't know about anyone else, but I don't shorten "economics" to "econs" so I'm not buying the "mathematics must be shortened to maths" line. Math is shorter than maths, so it's a more efficient shortenization. (That's American for "shortenisation," for those of you reading me from the United Kingdom.)

I got 7.
PEMDAS!
This was my favorite in math class. I really enjoyed these..i dont know why.

Why cant you use brackets for 2nd trations ( multiplication and division) and leave them for 1st trations ( addition and subtration)? that is how it's normally done.

juliesummers

the answer s 7 !!!!

and, "maths" ??!!!

goodness. :noway:

Maths is the abbreviated form of mathematics. It is not used in North America, but that doesn't make it incorrect.

Exactly what I was going to say^
