I Need Help Solving This Math Problem

[Natural Citizen]

 

[leftwinger]

I thought so so why was leftwinger saying that we were supposed to subtract first?

addition and subtraction are of equal importance. We must subtract first because the operation of subtraction comes before addition when viewed from left to right. I think the above was meant for a different example. But it fits yours in this case..

Subtration is not "first" but AFTER you get done with division, multiplication etc. then go left to right.
Subtraction was before addition. I know. It seems a bit weird. what if they were reversed? would you add first (after all the big ones (parathensasees, exponents, divide, multiply are done?)

What do you mean by that?

In a real world situation where you are hired as a book keeper or any position which system would you use?

I don't know what you're saying but I forgot that Natural Citizen had added the step that I forgot. If a PEMDAS equation doesn't have parentheses you're supposed to add them.

Is it bad that I still don't know what you're talking about when it comes to systems? I am SO bad at this.

Zero (Fruit Problem)

 

[Robert W]

So is it five or eleven guys? I'm confused.

11 is correct.

 

[Road Runner]

11 is correct.

I know now.

Subtration and Addition are equally importance. But then they say go "LEFT to RIGHT" so the subtraction was done first in the OP example.

funny. The easiest part is actually the hardest to understand and remember?

Ohhh my brain must be truly fried as I have absolutely no idea why I wasn't understanding what you were getting at.

The problem is meaningless because of the lack of parentheses separating the steps.

Then you use to the basic order of operations. If it was your TAX payment at stake would you balk so much?

Unless I have false memories from math class I think that you're supposed to add parentheses when a problem doesn't have them.

What it says is you need to use parentheses to prioritize the operations.

This problem seems designed to screw with the MDAS part of PEMDAS

And I always remembered is at "Please Execute My Dear Aunt Sally"

 

[Natural Citizen]

Oh yeah!! That's right if there's no parentheses you're supposed to add them.

Right.

You have to rewrite the equation to include them.

Dear Lord

None of this is difficult.

The answer is 11.

Yes, well, now we're just opining...Mr. Unsociable...

Numbed by Numbers

Too much math does make the brain explode. That's the story of John Nash (played by Russell Crowe in A Beautiful Mind). Just before his dementia, he was into the goofy and useless prime numbers.

Escapist math mind-candy also led the Unabomber to his delusions.

Yeah but you have to know where to put them.....thus the "ORDER of OPERATIONS" comes into play.
